BPEL to BPEL Synchronous Interaction.

As a continutation to my earlier 2 blogs about for Interaction b/w Mediator and BPEL Process (
Interaction1 
Interaction2
I will explain Interaction between BPEL 2 BPEL Process with simple example.

Complete Process -
BPEL Process 1 will call BPEL Process 2.Both are Synchronous processess.


In this example I will use Message Type "OrderInfo"  Message Type Element.Please Refer http://eoracleapps.blogspot.com/2009/11/how-to-call-synchronous-bpel-process.html for More Information on "OrderInfo" Message Type.

Import theMessage type in your Project and assign that to input and output variable of BPEL Process 1.


BPEL Process -1
Design BPEL Process 1 with simple Assign activity b/w input and output variables.


Design BPEL Process 2 , with simple Assign activity b/w input and output variables.Assign the message structure "OrderInfo" to input and output variable of BPEL Process 2.


Configure the Assign activity of Process 2 , by Double Click > Copy Operations > Copy i/p to o/p and copy Constant Expression "BPEL 2" to Status2 filed of message structure as shown below.






Open the BPEL Process 1 again and add INVOKE actvity in flow to call the BPEL process 2(BPELProcess3).



Configure the Invoke activity as shown below.



In Assign_1 activity in Process 1 , assign the input variable to input of the invoke activity as shown below.



Add another Assign activity in Process 1 , right below the invoke actity and assign the outcome of the invoke activity to output of BPEL Process.



Compile your Project and Deploy.

Testing - Run the BPEL Process and add the Input data ( Based on Order Info Element).


Verify the output.
