Subject: Fw: [wsbpel] Issue 11 - Call for Discussion
John, It suddenly hit me like a thunderbolt - duh! We need to add this use case as a BPEL use case, and develop the WSDL and BPEL example of the interaction with CAM. Does anyone have a transaction they want built as an example here? I can easily pick one I have - like the CAM template for the IV&I BOD and then the BPEL can query the warehouse subsystem to get the actual parts on hand data that then gets built out into the IV&I parts availability transaction format by the CAM template.
