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

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 ;) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4219619#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
