Configuration Durable Topic
Hello,
I have the problem configurating a durable Topic.
Can you tell me which JBoss-Files do I have to configure.
I'm using JBoss 3.2.1!
I have a message-driven-bean:
ejb-jar.xml:
<message-driven>
description>
<display-name></display-name>
<ejb-name>SQLListenerBean</ejb-name>
<ejb-class>com.jcoffee.base.sl.SQLListenerBean</ejb-class>
<transaction-type>Container</transaction-type>
<acknowledge-mode>Auto-acknowledge</acknowledge-mode>
<message-driven-destination>
<destination-type>javax.jms.Topic</destination-type>
<subscription-durability>Durable</subscription-durability>
</message-driven-destination>
</message-driven>
jboss.xml
<message-driven>
<ejb-name>SQLListenerBean</ejb-name>
<destination-jndi-name>jcoffee.jms.topics.SystemLoggingTopic</destination-jndi-name>
<mdb-user>john</mdb-user>
<mdb-passwd>needle</mdb-passwd>
<mdb-subscriber-id>DurableSubscriberExample</mdb-subscriber-id>
</message-driven>
jbossmq-destinations-service.xml:
<depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager
<depends optional-attribute-name="SecurityManager">jboss.mq:service=SecurityManager
jcoffee.jms.topics.SystemLoggingTopic
With this configuration it doesn't work. I think I forgot something but I don't know where.
If I start the JBoss-Server I always get exceptions like:
org.jboss.mq.SpyJMSException: Cannot subscribe to this Destination: null; - nested throwable: (java.lang.NullPointerException)
at org.jboss.mq.Connection.addConsumer(Connection.java:1094)

I don't have any experience with JMS / MDB.
Maybe someone can help me! Thanx!
