Handling service response in a standalone JMS client

[badlan]

I have a simple setup similar to the helloworld sample from the quickstarts. I am using a simple, standalone JMS client to dispatch a text message to a JMS gateway on which a ESB service is listening.

The JMS client blocks listening for service response on a reply queue (<request queue name>_reply).

According to the "Programmers Guide", and correct me if I am wrong, once the last action finishes processing the message, the action pipeline automatically places the message on the queue: (<request queue name>_reply), given that the actions mep attribute is set to RequestResponse in jboss-esb.xml.

If that is true, it is not working in my case. I am trying to figure out an optimum setup for such a scenario and so far, I could only get it to work by adding a JMSRouter action at the end of the pipeline.

Your help is appreciated. Thanks.

Hi badlan,

According to the "Programmers Guide", and correct me if I am wrong, once the last action finishes processing the message, the action pipeline automatically places the message on the queue: (<request queue name>_reply), given that the actions mep attribute is set to RequestResponse in jboss-esb.xml.

If the pipeline is specified with a MEP (Message Exchange Pattern) set to 'RequestResponse' then a reply will be sent to the ReplyTo EPR of the request ESB Message or, if a ReplyTo was not set set, a reply will be sent to the From EPR of the request ESB Message.
This means that your gateway would need to set the ReplyTo on the ESB Message by specifying a 'composer-class' for you JMS Gateway listener.

For your use case, I would use the JMSRouter like you have done. I think that is the simplest solution. If you've not seen it already there is a jms_router quickstart which also demonstrates message correlation in the ESB.

But let me know if this does not fit your requirements and I'll see if I can come up a different approach.

I want use the JMS approch too, but without the JMSRouter trick, because the service is used through the native ESB bus too.

Any advice?
