I have the following situation in an MQWorkflow environment. It is my belief that this problem is not due to MQWF.
I have a java program which recieves a message that requires a reply to FMCQM/EXEXMLINPUTQ on Host1. This program is required to send a message to FMCQM/EXEXMLINPUTQ on Host2. The following is what I am currently observing:
Application receives control with the appropriate Replyto QMGR/Q on Host 1.
Application sends message to Host2 by specifiying Host, port and channel.
Host2 performs its required task and returns to the App on Host1.
Host1 sends its reply (based on my log) but MQWF never recieves it.
Based on some testing we've done, I am pretty certain that what is happening is that the reply that is meant for Host1 is somehow being sent to Host2 and thus MQWF thinks the app is still running, I have not been able to proove this 100% but I am fairly certain that this is the case. I know if I remove the code from the Application that contacts Host2, the app sends its reply and MQWF is happy.
Not being really up on MQ, I am confused as to how this can be happening. IF anyone can shed some light on this I would be very appreciative.
THANKS.

In the last line - how application knows to reply to Host1 ?
When it get message from Host2 does it sends reply by ReplyQ/QM fields or specifically to host1 ?

I believe that I have found the problem. There is a static reference to the MQEnvironment and this is what is causing the problem. Once the hostname, channel, and port are set, they are never being cleared. I will mark this topic solved once my testing is complete, and post an update if I find that my current theory (static reference) is not correct.
THANKS
