TOP STUDENT PROJECT

Introduction to following Activities:

While Activity

Invoke Activity

OVERVIEW OF THE PROJECT:

We are going to select a top student from a list of students so we have to provide input as student detail & invoking a third party service ProcessStudentProcess which is discussed in previous DOC VI. This service process topper student request & provide response as a top students.

STEP W ISE PROCEDURE OF PROJECT TOPPER STUDENT PROJECT

Step 1: Create new project New --->All Technologies--->SOA Tier --->SOA project --->OK ---> Project Name (TopperStudentProject) ---> ADF Business Component---> SOA--->Next -->Empty Composite ---> Finish.Now you can see your project on left pane with all its contents so as we need to start our project with XSD .

Step 2: Create a new xsd file under project

Right click on xsd--> file name(StudentList.xsd) --> Target Namespace(http://www.bispsolutions.com/training/soa/schema/StudentList)-->

prefix (slobj) -->ok




now created successfully StudentList.xsd

Step 3: Design xsd as according to SCA i.e with the help of components or in design mode :

Click on element & rename it as TopperStudentRequest & press Enter key.

Step 4: Right Click on target namespace & click complex type




Step 5: Click on complex Type1 & rename it as StudentListType & hit Enter.




Step 6: Right click on StudentListType ---> insert inside complex Type-->sequence

Step 7: Click on element1 & rename it as Student & hit Enter




Step 8: Give Student element minoccur =1 & maxoccur =unbounded

Step 9: To import Student.xsd inside TopperStudentProject have two ways :

• Reuse xsd or wsdl by copying xsd or wsdl file physically from source project to target project directory

• Reuse xsd or wsdl by uploading from oramds repository

Now Right Click on target namespace & click import




Step 10: view on source mode & complete xsd import but before doing this copy Student.xsd from ProcessStudent Project ---> xsd ---> Student.xsd file to TopperStudentproject ---> xsd as shown below in sequence :




Now Successfully pasted Student.xsd inside TopperStudentProject --> xsd




Step 11: Click on Refresh twice or thrice

Student.xsd is now visible above StudentList.xsd




Step 12: Open StudentList.xsd & view on source mode & edit xsd import by writing namespace & schemalocation also register its namespace as shown below :

Step 13: View imported student xsd on Design mode as shown below:




Step 14: click on Student & and write its type as stdobj:StudentType in Property inspector located in right pane & hit enter

Step 15: Expand Student & observe design

Step 16: Right Click on target namespace & click complex type




Step 17: click on complex Type1 & rename it as StudentListResultType & hit Enter

then Right click on StudentListResultType ---> insert inside complex Type-->sequence

Step 18: : Right Click on sequence --->insert inside sequence--->element




Step 19: Click on element1 & rename it as TopperStudent & hit Enter

Step 20: click on TopperStudent & and write its type as stdobj:StudentResultType in

Property inspector located in right pane & hit enter

Step 21: : Expand Student & observe design




Step 22: Give Student element minoccur =1 & maxoccur =unbounded

Step 23: Similarly create another element TopperStudentResponse as shown below :

Step 24: : click on TopperStudentRequest & and write its type as slobj:StudentListType in

Property inspector located in right pane & hit enter




Step 25: Similarly click on TopperStudentResponse & and write its type as

slobj:StudentListResultType in Property inspector located in right pane & hit enter




Step 26: View Source mode :




Step 27: Right click on Composite.xml & click on open

Step 28: Create BPEL Process This composite .xml is partitioned into three sections

1. Exposed Services2. Components3. External refrences

Now right click on component section and choose BPEL Process




Step 29: Fill all its blank spaces Name (TopperStudentProcess) ---->NameSpace (Leave as it is)--->Template(Select Synchronous BPEL process)----> Service Name(TopperStudentService)----> mark Expose as a SOAP service ----> Transaction (required) ----> Click on Input Browse to select input of wsdl -----> & then Click on Output Browse to select Output of wsdl

On clicking input browse u can see as shown below

select TopperStudentRequest




On clicking Output browse u can see as shown below

select TopperStudentResponse




Step 30: Now we have created BPEL Process as shown below

Step 31 : Click on Source mode




Step 32: Since we have already created BPEL Process click on Composite on left pane

To create TopperStudentProcess.bpel click on TopperStudentProcess




NOTE: Since here we need to invoke third party service & so we have to create concrete ProcessStudent wsdl inside Topper Student Project




Step 33: Click on Oracle Home in linux Operating system as shown below :

Step 34: Open ProcessStudentdirectory & inside it copy ProcessStudentProcess.wsdl file




Step 35: Open Topper Student Project directory

Step 36: Paste wsdl file inside Topper Student Project :




Step 37: Open this wsdl file with Text Editor as shown below:

Visualization of wsdl file in Text editor




Step 38: Start Weblogic Admin server & deploy ProcessStudent Project because in above diagram wsdl is abstract & it contains only type, message type, port type, 7 partner link type so our motive is to make it concrete wsdl by adding information like binding ,services, etc.

Deployment Finished.




Step 39 : Click on Browser icon shown below:

Step 40: Start your enterprise manager by writing url http: //localhost:7001/em/

Note : Here localhost is application server & 7001 is a port in which enterprise manager is running.

Step 41 : Login using credentials User Name :weblogicPassword : welcome1click on login




Step 42: We have successfully login inside Enterprise manager 11g (Farm_dev_soa)we can clearly observe here that admin server is up & all deployment status is also up it means that our admin server is running .Now In left pane of window under Farm_dev_soa click on SOA radio button now again expand & under default we can easily see all the deployed projects. Click twice on ProcessStudent Project .




Step 43: Observe that all information regarding to ProcessStudent Project is given Running instances 0 means that yet we have not tested any instance.Total 0Project Status Active Now click on Browser tab

Step 44: Click on WSDL URL

Step 45: Now it is a Concrete WSDL , Right click on page & select View Page Source




Step 46: Copy namespace from here

Step 47: Paste namespace here in Text Editor




Step 48: Copy wsdl binding & service




Step 49: Paste here in Text Editor below wsdl port type as shown below :

Step 50: Click on Refresh twice or thrice

ProcessStudentProcess.wsdl is now visible above TopperStudentProcess.bpel




Step 51: Click on ProcessStudentProcess.wsdl in left hand pane & On clicking ProcessStudentProcess.wsdl we can see automatic generated wsdl file

Step 52: Click on Design Mode & design of service is shown below:

Step 53: To create third party service ProcessStudentProcess as Reference, right Click on External references & click on web service




Step 54: fill all relevant blank as shown below then click ok.

Step 55: Right click on partner links & click on Create partner link




Step 56: Name as ProcessStudent Reference & click on browse for wsdl URL

Step 57: Select Process StudentReference & click ok

Step 58:Now as we select wsdl url all other field will auto fill then click okas shown below:




Successfully created Partner links & references

View composite BPEL Processweb service consumer & web service provider is wired with BPEL process as shown below




Step 59: View TopperStudentProcess.bpel in source mode & observe all important components :




Step 60: Click on Variable icon & create new variables IndexVar ,CountVar &

TopMarks

then CountVar




then TopMarks




Finally check assigned variables & click ok .

Step 61: Drag & drop While Activity between receive input & reply Output .

NOTE: While Activity is used for looping purpose .




Step 62: Drag & drop assign activity & click twice on it as shown below:

Step 63: Explore Functions ----> BPEL XPath Extension Functions ----> CountNodes--->Insert Into Expression--->select Student under Input Variable---> Insert into expression .Delete bpws:getVariabledata which is shown by green box




Step 64: Now xpath expression is set for countVar , Click OK

Step 65: Click Expression Drag it & keep it in IndexVar under Variables




Step 66:Initialize index as 1

Step 67: 66:Initialize TopMarks as 0.




Step 68: Assigned varibles are shown below then click Ok

Step 69: Now we have assigned all variables & rename it as AssignTemp.




Step 70: Click on Expression icon

Step 71: Assign looping condition here Click IndexVar ---> insert into expression ---> Less equals --> insert into expression ---> CountVar---> insert into expression---> Click Ok




Step 72: Click OK

Step 73: Drag & drop Invoke activity & click twice on it as shown below:

Step 74: Fill Name (InvokeProcessStudent) then browse for Partner link




Step 75: Select ProcessStudentReference & click OK

Step 76: To select Input & Output to invoke ProcessStudentReference Click on first green plus sign for input & likewise for Output

Step 77: After Selecting Input & output click ok .




Step 78: Check all filled entries & click OK

On clicking Ok this window will appear & a wiring established between InvokeProcessStudent & ProcessStudent Reference

Step 79: Drag & drop Assign Activity & Rename It as AssignInvokeInput & then Click it twice :




Step 80: Assign input elements from Input variable to ProcessStudent_inputVariable then click Ok as shown below :




Step 81:Click on BPEL source mode & insert [$IndexVar] after Student so as index changes student changes & so easily we can input infinite number of students




Step 82: In design mode Drag & Drop Switch Activity so that bpel can set condition

MOTIVE OF SWITCH ACTIVITY : Our motive is setting condition that if total >= Top Marks then assign topmarks otherswise increment index & check for other student & finally assign invoked processed outputfrom third party service provider to reply Output to the service consumer .

Step 83: Browse under BPEL Variables ProcessStudent_OutputVariable ---> expand it & select Total --->Insert Into Expression ----> Browse under Functions-->AdvancedFunctions ---> Logical Functions---> greater equals ----> Insert Into Expression----> Browse under BPEL Variables TopMarks---> Insert Into Expression---->Click ok




Step 84: Click ok

Step 85: Drag & drop Assign Activity & Rename It as AssignTopMarks & then Click it twice :

Step 86: Assign from ProcessStudent_OutputVariable then Total To TopMarks & click OK




Step 87: Drag & drop Assign Activity & Rename It as AssignOutput & then Click it twice :

Step 88: Assign Output elements from ProcessStudent_OutputVariable to Reply OutputVariables then click Ok as shown below :




Step 89: Drag & drop Assign Activity & Rename It as AssignIncrement & then Click it twice:

Step 90: : Click Expression Drag it & keep it in IndexVar under VariablesNow click on index Var under BPEL Variables ----> Insert Into Expression ---> +1 --> Ok

Step 91: Click Ok




Step 92: Assign out put completed & also BPEL process completed Now Click on Complile Icon shown below:
