I am using JMS over MQ for asynchronous messaging. I use setMessageListener method to start a listener on a specific queue so that when the response (which is in Copybook format) comes the onMessage() method will pick the same. The onMessage() method after receiving the response again starts the listener to receive the next response. So there is continously a listener waiting on the queue.

After picking up the response I have to convert the message from Cobybook to XML. In case there is any problem I want to rollback the message back to the queue, on which I have set the listener.

My problem is,
1. How to rollback a message once it is recived by a listener?
2. After rollback will the next listener is capable of reading the message?

Please read up documentation on J2EE and JMS as well on JMS listeners.
This is not the way the JMS listeners work.
At the same time read up on EJB and JMS transaction model.
All answers are there.

Thanks
