How to call PL/SQL Procedure from BPEL

This is a Simple blog where I explain
1.How to Create a DBAdaptor (Partner link) in BEPL to call a PL/SQL  procedure .
In case visibility is not clear , double click the screen Shot.

Lots of such examples available at www.oracle.com

Step -1  Create a BEPL Application in JDev11g.




 
Make Sure it is Synchronous template.
 


Step - 2
Drag Database Adapter and configure it.
 
Step 3
Select the Operation Type.
In my example it is "Call a Store Procedure/Function".
 
Step 4
Select the Procedure.

 

Step5
Drag Invoke activity in the BPEL flow and then Invoke the DB Adapter from it. 
 
Step 6
Our Process is ready , Now to make this BPEL flow work , I add to dummy Assign activity in the flow.
Assign_1 and Assign_2
Assign_1 - This will assign the input variable to Input variable of Invoke activity.

Assign_2 - This will assign the output variable of Invoke activity to output variable of BPEL Flow.

Why I called them as dummy activity , because I am not using values input to this process any where .
My example PL/SQL Procedure has one INSERT Clause that just Insert hardcoded values in table.

 

I/p variable for Invoke activity.
 

Step 7
Copy functionof ASSIGN_1 , it just copy input variable of BPEL process to Input variable of Invoke activity.

Step 8
Add Assign_2 and perform COOPY operation.
 

Step 9 - Complete Process
 
Step 10 - Deployment

 

Step 11 - Testing -1
 
Step 11 - Testing -2
 

Step 11 - Testing -3
 
Step 11 - Testing -4
