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 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 Services
2. Components
3. 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 :weblogic
Password : welcome1
click 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 0
Project 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 ok
as shown below:

Successfully created Partner links & references
View composite BPEL Process
web 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 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 Variables
Now 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:
