    MDB with durable subscription help

    a d Newbie

      Hello,

      I try to run a simple MDB that is listening to a Durable Topic.
      But when I deploy it in Jboss4.0.0 I have got the following error:

      javax.jms.JMSException: Null or empty subscription
      at org.jboss.mq.SpyConnection.createDurableConnectionConsumer(SpyConnect
      ion.java:151)

      I think I miss something in the configuration of Jboss in particular for the durable Topic . If someone can help me

      I saw that it was usefull to add the name of our topic in conf/jbossmq-state.xml. I did as follow:


      XferRequestTopic


      here are my ejbjar.xml and jboss.xml files:

      <ejb-jar>
      
       <description>Deployment descriptor about Oriade EJB application</description>
       <display-name>OriadeEJB</display-name>
