Hi,
I am trying to setup a scenario where, Invoke activity sends a SOAP/JMS message to an WMQ queue and waits for the reply to come before proceeding. This is an actually synchronous implementation of SOAP/JMS.
Even though it looks simple, I am not able to setup the system to work synchronously.
In the assembly diagram, I will have only import and no export as it is a sync and I expect the message to be returned to some q.
When I run the application, it sends out a message to an external Q and I am not sure, where to send message back as there is no listener running on WPS to receive it(make sense bcos there are no exports or deployed code did not created any reply Q).
It may be my lack of knowledge in how to setup the infrastructure. If somebody worked on it, please share. Or if u guys know of any link that gives an instructions on how to model a invoke activity with sync SOAP/JMS that would be great.
Thanks,
-Mahesh |

Thanks Vennela.
I have gone through that examples. That example implements jms binding where we send the pure JMS message. I am looking for implementing the SOAP/JMS(Webservice binding).
In JMS binding we don't need the corelation set as we define one more queue on the WPS which will keep track the instances based on the MQ co-relationID.
As you mentioned, we need correlation set for implementing the Async Soap/jms. When I say Async, there will be 2 one way interfaces.
One to send the message to an external Q and one for reply message.
On BPC we will have either receive or receive choice(PICK).
The above method works because, we have an receive activity and an 'export' in the assembly diagram.
I am trying to see, whether I can implement the same with twoway interface.
I found from IBM that, it was not supported in WAS 5 but not sure with WAS 6.
"Web Services Invocation Framework (WSIF) supports the request/response pattern by allowing asynchronous request/response operations. In this mode of operation, the client puts the request message as part of one transaction, and carries on with the thread of execution. The response message is then handled by a different thread, with a separate transaction. Note that SOAP/JMS is not supported for request/response pattern. "
Thanks,
-Mahesh |

| And with WAS6, WSIF is deprecated I guess. |
