    durable topic subscriber (using EJB3 annotations)

    Joe W Newbie

      I have researched this for a while now with no luck so here goes . . .

      I am trying to deploy a durable topic subscriber using EJB3 annotations. The MDB is deployed fine and it processes messages fine as well. The issue is that the subscription is showing as non-durable (as seen in the JMX console when I look at the subscribers and there is no entry in the db table JMS_SUBSCRIPTIONS).

      I am using jboss-4.0.4.CR2 with EJB3 - jboss-EJB-3.0_RC5-PFD and java 1.5.0_06-b05.

      Here is code snippet where I define my MDB:

      @MessageDriven(activationConfig =
      {
       @ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Topic"),
       @ActivationConfigProperty(propertyName="destination", propertyValue="topic/testDurableTopic"),
       @ActivationConfigProperty(propertyName="subscriptionDurability",propertyValue="Durable"),
       @ActivationConfigProperty(propertyName="clientID", propertyValue="subscriber3")
      })
      public class TestSubscriber implements MessageListener { ... }
      



      I have not changed the configuration of the testDurableTopic that comes with JBoss; it still persists to the Hypersonic database.

      In the client application that I am using,
      1. I set the publisher delivery mode as persistent [e.g., publisher.setDeliveryMode(DeliveryMode.PERSISTENT)]
      and
      2. I set the JMS delivery of the message [e.g., message.setJMSDeliveryMode(DeliveryMode.PERSISTENT)].

      When I print out the message contents I see jmsDeliveryMode : 2 (e.g., PERSISTENT).


      As mentioned above, I have been researching this for a while (days); I have read through a lot of documentation; I turned on debug tracing; I looked in the JMX console; etc. - but no luck.

      The page that fits this topic well is out of date (found here): http://wiki.jboss.org/wiki/Wiki.jsp?page=WhatIsTheCorrectWayToMakeADurableSubscription

      I was able to create a durable subscriber programmatically using
      session.createDurableSubscriber(topic, clientId);
      


      But this does not seem like the correct way to create durable MDB subscriber; this just created a different receiver. Please correct me if I am wrong but the annotations should allow me to create a durable subscriber without creating one programmatically as above.

      Any help grealy appreciated. Thanks in advance.
