[jboss-user] [EJB/JBoss] - Re: MDB 'at most, once' delivery (Ack before onMessage)

[serquicia]

Can't you set up the queue so it only attempts to deliver it once.

In JBoss Messaging it would be something like:


  |    <mbean code="org.jboss.jms.server.destination.QueueService"
  |    	name="jboss.messaging.destination:service=Queue,name=SomeQueue"
  | 	xmbean-dd="xmdesc/Queue-xmbean.xml">
  |       <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends>
  |       <depends>jboss.messaging:service=PostOffice</depends>
  |       <attribute name="MaxDeliveryAttempts">1</attribute>
  |    </mbean>
  | 

If the delivery isn't successful, the message will end up in the dead letter queue.

Hope it helps ;)
