infinite message redelivery between Queue and MDB

maximep May 5, 2011 12:03 PM

Hello,

I'm having a problem with a JEE Application which is consuming JMS messages via MDBs. I'm working with JBoss 6.0.0Final.

When the MDB throws an exception while processing his onMessage() function, the message cannot be pulled away from the JMS Queue, and HornetQ keeps trying redelivering it infinitely.

I'm not the one who configured this server, so I don't really understand how I should change this behaviour. Actually, I accidentally sent a Message with a wrong object inside, and it's logical that the MDB rejects it. I would like to know how to flush the JMS Queues/Topics, or how to make the MDB accepting the message even if it throws an exception, since HornetQ saves the messages when shutting down JBoss. I can't get ridd of these buggy messages...

Thanks!

Look at hornetq-configuration.xml

There's the address settings using wildcard.

You can either add this:

   <address-settings>
      
      <address-setting match="jms.queue.YourQueueName">
         <dead-letter-address>jms.queue.YOURDLQ</dead-letter-address>
         <max-delivery-attempts>3</max-delivery-attempts>
      </address-setting>
   </address-settings>

Or you can add these two lines to the # matching:

         <dead-letter-address>jms.queue.YOURDLQ</dead-letter-address>
         <max-delivery-attempts>3</max-delivery-attempts>

It's a known bug in JBoss AS 6.0.0.Final https://issues.jboss.org/browse/JBAS-7950 and has been fixed in the latest AS 6.1.0 SNAPSHOT http://community.jboss.org/thread/161386

Jaikiran,

Can the bug fix be integrated into JBoss 5.1.0 or is it necessary to switch to JBoss 6.1.0 for this fix ?

Thx.

JBoss AS 5.1.0 doesn't use HornetQ. So that bug doesn't apply for JBoss AS 5.1.0.

Thanks for your support.
I solved the problem by replacing the message journal files by empty ones... This is a quick fix intended for testing use only, that I'll use until I switch to JBoss 6.1.
