fOlks,
another doubt..
suppose I am logging a message..
so, I will not be spawning up a listener in the sender side, right?
so, the sender will put the log message ito the queue and some listener in the other side will pick it up and log into flatfile/dbase.
my doubt is what if this log message put into the queue, expires? or rather if this is timed out.. what will happen?
will my sender module still get something like a status message? or rather how's that possible? as I don't have a listener at sender side even to get the time out status message back..
I am confused, guys..
help me out..
Thankx in advance

Well, as far as protecting against the message expiring on the queue, you can set the expiry of the message when you create it. This way, you can set an infinite expiration time, which means the message will never expire. Also, you can utilize what is called COA/COD to inform the sending application when the message has arrived at the destination queue, and been picked up by the listening application.

Thankx Duncan for the fast reply..
but I am using MQ JMS APIs.. I don't know if the message sender will ever get something like that in this case. well.. i don't know.. I am doubtful about this only because I am not spawning up a listener thread for a time out status message. so, just wondering how I'll get that time out info. I am not using MQ APIs..
Thankx in advance

Unfortunately, most of my experience with Java/MQSeries is via the MQI interface, not JMS. Perhaps someone else knows the answer to this? (madly tapping SOS against the monitor)

Have a good read of the Using Java manual as part of MA88. You will find in there the JMS_IBM_Report_Expiration property of a message. This can take one of the following values:
MQRO_EXCEPTION
MQRO_EXCEPTION_WITH_DATA
MQRO_EXCEPTION_WITH_FULL_DATA
If the message expires, a response message will be sent to the reply queue.

But beware. The Message Expired reply will only be sent when a GET (or browse) is done against the queue where the message is. So, if no GET is done, no reply will be sent.
Cheers,
