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 WISE PROCEDURE OF PROJECT TOPPER STUDENT PROJECT

Step 1: Create new projectNew --->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 ourproject 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



3/73

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 asTopperStudentRequest & press Enter key.

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



4/73

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



5/73

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

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



6/73

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 targetproject directory

Reuse xsd or wsdl by uploading from oramds repository

Now Right Click on target namespace & click import



7/73

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 :



8/73



9/73

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



10/73

Step 11: Click on Refresh twice or thrice

Student.xsd is now visible above StudentList.xsd



11/73

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:



12/73


13/73

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



14/73

Step 19: Click on element1 & rename it asTopperStudent & hit Enter

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

Property inspector located in right pane & hit enter

Step 21: : Expand Student & observe design



15/73



16/73

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

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

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

Property inspector located in right pane & hit enter



17/73



18/73

Step 25: Similarlyclick onTopperStudentResponse & and write its type as

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



19/73

Step 26: View Source mode :



20/73

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

Step 28: Create BPEL Process

This composite .xml is partitioned into three sections1. Exposed Services2. Components3. External refrences

Now right click on component section and choose BPEL Process



21/73

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

On clicking input browse u can see as shown below

selectTopperStudentRequest



22/73

On clicking Output browse u can see as shown below

26/73

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

To createTopperStudentProcess.bpel click onTopperStudentProcess



27/73

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



28/73

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

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



29/73

Step 35: Open Topper Student Project directory

Step 36: Paste wsdl file inside Topper Student Project :



30/73

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

Visualization of wsdl file in Text editor



31/73

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

Deployment Finished.



32/73

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 isrunning.

Step 41 : Login using credentialsUser Name :weblogicPassword : welcome1click on login



33/73

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 meansthat 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 .



34/73

Step 43: Observe that all information regarding to ProcessStudent Project is givenRunning instances 0 means that yet we have not tested any instance.
