1. Re: Duplicate messages
adrian.brock Sep 18, 2003 6:29 PM (in response to peterpurmonen)JBossMQ is allowed to redeliver a message if you
failed to acknowledge it.
You can check for this circumstance using
message.getJMSRedelivered();

2. Re: Duplicate messages
javajedi Apr 30, 2004 2:39 PM (in response to peterpurmonen)I am seeing this same behavior. It is extremely sporadic. I am only seeing it happen for roughly 1 in every 500,000 messages in our automated build environment. So far, I have been unable to duplicate the problem locally. I added a check for getJMSRedelivered(), but it is returning false on the duplicate messages. This looks like a bug to me. I will continue to work on trying to track it down, but any debugging tips would be appreciated.

5. Re: Duplicate messages
adrian.brock May 1, 2004 5:10 PM (in response to peterpurmonen)If it is doing what you say, it is a bug.
But don't claim a bug unless you substantiate your claim.
The only mechanisms for a message to get back into the queue after a delivery
involves JBossMQ setting redelivered to true and setting the redelivery count.
Also, do not hijack somebody else's thread if you want to keep your forum account.
