CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams

122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

administrator and 6 different functions for users Refer
to Figure 2 is the Use case Diagram of this project
51 Graphical User InterfaceRequirement
User interfaces for the Online Multimedia
Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password
By click Submit button it will submit the Login name and
password by HTTPS to server and processing login servlet

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

administrator and 6 different functions for users Refer
to Figure 2 is the Use case Diagram of this project
51 Graphical User InterfaceRequirement
User interfaces for the Online Multimedia
Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password
By click Submit button it will submit the Login name and
password by HTTPS to server and processing login servlet
The system will forward current user to Main Page according users role which is administrator or user

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema

MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server

CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5

PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

322 Product Functions
Figure 2 Use Case Diagram
10
323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)
9
322 Product Functions
Figure 2 Use Case Diagram
10
323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

PROJECT IMPLEMENTATION
OMCS is designed to perforin 7 different functions for
administrator and 6 different functions for users Refer
to Figure 2 is the Use case Diagram of this project
51 Graphical User InterfaceRequirement
User interfaces for the Online Multimedia
Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password
By click Submit button it will submit the Login name and
password by HTTPS to server and processing login servlet
The system will forward current user to Main Page according users role which is administrator or user

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER ONE
INTRODUCTION
11 Purpose of This Project This project is a web-based application that
provides a friendly and simple interface to let users
easily upload and download their multimedia files ordered
by locations The records are shared with not onlyauthorized users but also with administrators to the site
The project includes two parts one is a normal web
browser which uses HTML (Hyper Text Markup Language) as
the basic interface language The other one is server The
users can upload download and modify their files to
server and modify their personal information on the siteAll the information is stored in a MYSQL database andretrieved by JSP using JDBC or JSTL
Online Multimedia Communication System is an easy to
use web-based application Everyone knows how to use a
web browser so they can login to upload their multimedia
files or view the files on Download File page which
other users uploaded to server
12 Scope of Project121 Deliverables
The project has produced the following artifacts
1
1 A web application project directory organized according to the standard layout described inTomcat (httpjakartaapacheorgtomcat)
2 Java build file that compiles all java code and
generates javadoc
3 Javadoc for source code developed for system4 SQL creation scripts that create the database
5 Project report containing various UML diagrams
such as class diagrams use case diagrams
deployment diagrams etc
122 Function of Software ProductsThis system allows the users to modify and update
information from a normal web browser Users also uploadand download multimedia files to share Business andfamilies want to share their photos videos and audio
recordings
13 Significance of the Project We live in a global society where communications with
family and business associates must be maintained across
time zone and national boarders This project meets the
challenge of providing user-friendly interfaces to shared
data Online Multimedia Communication System makes use of
current technologies to increase reliability and
2
efficiency in the creation and execution of real-life
proj ects

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)

322 Product Functions
Figure 2 Use Case Diagram
10
323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema

Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)
9
322 Product Functions
Figure 2 Use Case Diagram
10
323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

CHAPTER FIVE
PROJECT IMPLEMENTATION
OMCS is designed to perforin 7 different functions for
administrator and 6 different functions for users Refer
to Figure 2 is the Use case Diagram of this project
51 Graphical User InterfaceRequirement
User interfaces for the Online Multimedia
Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password
By click Submit button it will submit the Login name and
password by HTTPS to server and processing login servlet
The system will forward current user to Main Page according users role which is administrator or user

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)
9
322 Product Functions
Figure 2 Use Case Diagram
10
323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

PROJECT IMPLEMENTATION
OMCS is designed to perforin 7 different functions for
administrator and 6 different functions for users Refer
to Figure 2 is the Use case Diagram of this project
51 Graphical User InterfaceRequirement
User interfaces for the Online Multimedia
Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password
By click Submit button it will submit the Login name and
password by HTTPS to server and processing login servlet
The system will forward current user to Main Page according users role which is administrator or user

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places

CHAPTER TWO
ONLINE MULTIMEDIA COMMUNICATION SYSTEM
ARCHITECTURE
In this chapter I will briefly introduce this
project OMCS implements a web system that provides an
environment for users to store and share their multimedia
files The system is a 3-tier-distributed architecture
that displays the user interface to a web browser using
JSP The middle tier is the Apache Tomcat web server that
handles requests from the client browser and provides
access to the third tier MySQL via JDBC
The web application executes a user command
bull User types a URL in web browser
bull - Request is transmitted to web server via HTTPS
protocol
bull Web server response to the request and executes
from a JSP page and loaded by the JSP engine
bull Java business logic communicates with database
via JDBC
bull JSP generates custom HTML documents or generates
custom WML documents and sends them back to the
user via the HTTP protocol
5
The user interface components are built by using HTML
60 forms HTTPS frames and JavaScript The application
is implemented using Java Server Pages (JSP) JSP was used
because it can use java business logic and provides a
common way for programs to interface with java containers
JSP is an extension of Java Servlet technology Typically
a Java Servlet can do the same tasks as JSP however JSP
makes it easy to mix static HTML with Java code
The database choice available to OMCS is MySQL MySQL
is a real multi-user database and free Also the
availability of the JDBC driver for MySQL is the most
important reason to choose it Moreover the same code
could be used to link with another version of MySQL
database by changing the JDBC driver thereby making it
database independent

CHAPTER THREE
SOFTWARE REQUIREMENTS SPECIFICATION
31 Introduction
Online Multimedia Communication System is a project
aimed at providing people the ability to upload and
download their multimedia files These users can modify
and view the site from a normal web browser and also
share the event files to other users
32 Overall Description
321 Product Perspective
Online Multimedia Communication System is web based
The interfaces are via Internet
The hardware interface requirement is that it must
run on the existing web servers The software interface
requirement is that it must support current versions of
Netscape and Internet Explorer The communications
interface requires support for Hyper-Text Transfer
Protocol by SSL (HTTPS)
9
322 Product Functions
Figure 2 Use Case Diagram
10
323 Product ArchitectureThe system contains three main parts of architecture
client side machine web server and database(1) Client side machine It requires having Internet
Brower and Internet connection This machine can connect
to web server by HTTPS protocol
(2) Web Server This project uses Linux 90 as the
operating system and Tomcat web server It establishescommunication between server and client machine and also
between server and database Java servlet is executable in
the server
(3) Database MySQL database is used in this project
To connect database we use Java Servlet to control when
to access the database and which information to access

CHAPTER FOUR
DATABASE DESIGN
41 Data AnalysisThe data for designing and implementing the schema of
the database depends on properties of user In designing
the schema for the OMCS database four distinct parts have
been identified The first includes file part which
includes file name file path location id size created
date create time last access date last access time and
user id The second includes user id user name and user
password which would always be encrypted before storage
All the entities and attributes are detailed in Figure 5
13
PASSWORD
CZZ^ffectdate
Figure 4 Entity Relationship Diagram
14
There are some things one may not see from the E-R
Diagram and I will explain more The field of USERID in
both file and location has to match For example USER_A
owns LOCATION_A and LOCATION_B For all files owned by
USER_A must belong to either LOCATION_A or LOCATION_B
There is a function Remove User for administrator
When an administrator removes a user all locations and
files which belong to that user will automatically
belong to administrator
42 Database Schema Logical Model - Relational Schema
The conceptual model ER diagram maps into the
following relational table design In the following
tables underlined fields indicate the primary key

CHAPTER FIVE
PROJECT IMPLEMENTATION
OMCS is designed to perforin 7 different functions for
administrator and 6 different functions for users Refer
to Figure 2 is the Use case Diagram of this project
51 Graphical User InterfaceRequirement
User interfaces for the Online Multimedia
Communication System are designed as HTML pages The
contents are generated dynamically by JSP in response to
the users requests OMCS GUI is an easy to use system
The GUI is written using Hyper Text Markup Language (HTML)
Version 60 forms The OMCS GUI is executable under
Internet Explorer 50 or greater The following
sub-section explains the GUI functions and details
52 Graphical User Interface Normal Browser Website
521 Login Page
This page is the first page that all the users see
when they enter OMCS This page offers the login function
and a link to register new account (1) Registration This
link is for a new user who want to register new account in
OMCS By click this button user will be link to Register
page (2) Login name amp Password In these two boxes
20
current users can fill out their Login name and Password
By click Submit button it will submit the Login name and
password by HTTPS to server and processing login servlet
The system will forward current user to Main Page according users role which is administrator or user

After the user clicks Download Files link on Main
Function page the user goes to the Download Files page
Users and Administrators can view all multimedia files in
the system on this page and also save these event filesto local machine
27
It also displays the owner of these files so user
can easy to know who share those events with them
After current user finished updating personal
information he or she can click the link Main Page
which is on the bottom of this page to go back to Main
Page

28
526 Upload File Page (For both Users andAdministrators)
Upload File Page allows user to upload their files by
different locations There are two parts in this page One
is to select a location and the other is to upload files
The locations option lists all locations which
belong to the current user After user selects one the
system will save the location ID in session User can
selects a file to be uploading to server After submit
the system will store the file to server and list the new
file information in the current page
In this system users can upload different types of
files but in the Download Files page only can play the
AVI format For the other files such as photos audios
and other type of video files user has to save those
files in local machine for viewing or playing User and
Administrator can keep uploading files as many as he or
she wants
The information displayed on the right is current
users personal information There is Main Function link
in the bottom of web page User can click the link and
link back to the Main Function page
29
Figure 12 Upload Files Page (For both Users and Administrators)
527 Setup New Location Page (For Administrators)Setup New Location Page allows administrators to
modify all users location information After users applynew locations locations status initially setup as nonshyactive Only until administrator active those locations
30
users will be able to upload event files for those
locations
In the location selection it shows description of
these locations Administrator can modify all the data for
this location beside location ID Location ID is given
when user applies new location by system

CHAPTER SIX
MAINTENANCE MANUAL
System maintenance is an important step to ensure
that the system runs smoothly and meets the expectation of
the users In this project there are 3 major issues
Software Installation Variables Modification and OMCS
Installation
61 Software Installation
OMCS requires MYSQL TOMCAT and JDBC to run The
following will detail the installation of these software
packages
611 JAVA 2 Platform Standard Edition
JAVA 2 Platform Standard Edition (J2SE) is the
compiler program for JSP programs and the TOMCAT Container
requires it First of all we go to
httpjavasuncomproductsarchivej2sel4l_07 to
download SDK Windows (all languages including English)
and then install it
612 Structured Query Language Installation
Structured Query Language (MySQL) is the database
system we use in the OMCS and it is free Because it also
provides JDBC to easily connect by JAVA program thus it
is good choice for designing this project The
41
installation of MYSQL 323 is included in Linux 90 We
also can download it from Internet at
httpwwwmysqlcomdownloadsmysql-323html If users
download the compress file from Internet please unzip the
file and install it Second in Linux command we type
gt etcinitdmysqld start
It starts MySQL in server Third we have to add
etcinitdmysqld start into the file rclocal It
will start MySQL every time when we restart linux server
Forth we run MySQL on server to edit database by typing
gt mysql javatest -u javauser -p userdatabase
Enter passwordmysql_password
After that we can try to input following command
mysqlgt select from user
mysqlgt exit
gtThen we have already installed MYSQL and its working asexpected
613 Java Database ConnectivityThe API used to execute SQL statement is different
for each database engine Java programmers however arebecause they free from such database portability issues
They have a single API the Java Database Connectivity API(JDBC) thats portable between database engines The JDBC
42
library provides an interface for executing SQL statements
It provides the basic functionality for data access A
number of drivers are available for MySQL and information
about this can be obtained at the MySQL homepage at
httpwwwmysqlcomdownloads under JDBC For our
purpose we will use the MySQL driver which is a Type-4
JDBC driver that is under the GNU Library License
614 TomcatTOMCAT is one of the Jakarta apache projects it is a
JAVA container to process JSP programs and construct a web
server for static web pages First of all we go to
httpapachemirrorcentralcomdistjakarta
tomcat-4binaries to download the file tomcat-4118zip
and extract it to hard driver Also we copyCtomcatbinstartupbat and shutdownbat to the desktop as shortcut in order to easily start and shut down tomcat
615 Secure Sockets LayerThe security of this web site is very important for
this project In this part we are going to show how to set
it up This system uses HTTPS by Java Secure Socket
Extension (JSSE) In TOMCAT server you have to setup some
configuration file to activate HTTPS There are some filesyou need to modify serverxml netfiltersh rclocal
and iptables
43
First we have to generate the key we can type
gt keytool -genkey -alias name -keystore pathandname
First the system will generate the key and store it
as the path and name you type above Second we have to
change the serverxml file We have to add connector for
https To do this we have to add redirectPort=8443 in
the connector Third we have to add a line iptables -A
INPUT -p top --dport 8443 -j ACCEPT so the system will
aceep the 8443 as connect port Fourth we add a line in
iptables file
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8443 -
syn -j ACCEPT
This line will open port 8443 as a TCPIP standard
for connection Fifth we add a line rootnetfiltersh
in rclocal file so after rebooting server it will run
set https as acceptable port for server
44
CHAPTER SEVEN
CONCLUSION AND FUTURE DIRECTIONS
71 Conclusion
In the project OMCS provides a perfect environment
for user to upload download and view all users event
files over web browsers The system uses Tomcat Web Server
running on Linux platform with MYSQL database I
implemented the system using JavaScript JSP HTML and
JSTL languages and I implemented the advanced presentation
feature within the browser using JavaScript All dynamic
contents are handled by JSP The main logic was written in
Java and a data Source was used to connect to the
database
Online Multimedia Communication System is an easy to
use system of a Web-based application Everyone knows how
to use a web browser so they can login to system and
upload download and view all users event file online
There are also some disabilities for Online
Multimedia Communication System First the location
cannot be removed from the database When a user applies a
new location the location record will be in database If
an administrator removes the user the administrator will
automatically own the locations
45
Second there is no way to create an administrator
The administrator cannot be created by this system The
new register persons will automatically setup as users
72 Future Directions
The possible improvements that can be made for OMCS
include the following
To make the graphical user interface friendlier OMCS
aims to provide a friendly user interface but there are
still many possibilities for improvements For example
adding an OMCS picture icons in each pages to make the
entire page richer Change the format of the tables such
as Register page
For more OMCS system can be fit for doing Security
Guard for future Nowadays web cam is very popular and
its functions are very well For myself my web cam is
lax When I it setup as Guard Mode if the image in
front of the video changed it records the images into a
video file in a fixed path If we can change the Upload
Page by automatically upload from this folder this system
can become a security guard system for users
In future developments the system will be more
flexible to be installed for various places
