HI,
I am using MQseries 5.2 with MQSeries classes for Java Message Service (JMS) V5.21 on WINNT machine.
I have open the session as connection.createQueueSession(transacted,Session.AUTO_ACKNOWLEDGE)
and when the message is received on the receiver's onMessage method then I am getting MQJMS1057 on trying to do the message.acknowledge().

javax.jms.IllegalStateException: MQJMS1057: Message has no session associated with it
at com.ibm.jms.JMSMessage.acknowledge(JMSMessage.java:3233)

Can anybody provide some inputs to this???

Thanks and Regards
Amit

Hi
The problem is that if session is created as Session.AutoAcknowledge I shud not be acknowledging the message but if I dont acknowledge the message the message is backed out.

I have a typical asynchronus request reply scenario

Application 1 - creates a request message. It creates the temporary queue and set the setJMSReplyTo field with that value, and also set the message listener to itself to listen on temporary queue and send the request (say request on Queue named Queue.TempQueue).

Apllication 2 which is listening on Queue.TempQueue receives the message and process it and send the reply back to the Temporary Queue as defined.

The problem which I am facing is that all the things work fine but the message remain on the "Queue.TempQueue" with its backout count increases. and if try to call message.acknowledge from the application2 I get the MQJMS1057 error.

Also one intresting observation is that say Application2 keep on running then if I again send messages again and again then everything is working fine. but if I try to close the session within the onMessage method in Application 2 I get the messages backed out.

Thanks and Regards
Amit
