    JMS between 2.4.9 and 2.4.4

    Stefan Wiese Newbie

      Hi,
      I upgraded a JBoss from 2.4.4 to 2.4.9.
      Before I upgraded, JMS works fine.
      After upgrade all other things work fine, but for JMS I can't get a TopicConnectionFactory per lookup on a remote machine with a running JBoss 2.4.4.

      here is some code..

      Context context = new InitialContext(props);
      // Get the connection factory
      TopicConnectionFactory topicFactory = (TopicConnectionFactory) context.lookup("TopicConnectionFactory");
      // Create the connection
      topicConnection = topicFactory.createTopicConnection(); //here is NullPointerException thrown

      There is no exception thrown, only a NullPointerException, when trying to use this TopicConnectionFactory-Object to cretae a TopicConnection.
      Like I said, with JBoss 2.4.4. everything is ok. There are NO changes to the sourcecode.
      Can someone help me?
      Thanks
      McAlm

            There is no meaningfully stacktrace available, only this:

            This NullPointerExyception occurs when trying to create a TopicConnection with the TopicConnectionFactory.
            Running the JBoss 2.4.4. it can commúnicate with the other JBoss 2.4.4. But running the 2.4.9, this exception is thrown.

              It looks like the NPE is in your code?

              java.lang.NullPointerException
              at de.xxx.yyy.session.AuftragTransferSessionBean.sende(Unknown Source)

              Are you trying to invoke between 2.4.4 and 2.4.9?
              It might be that one of classes has changed
              incompatibly.
              One obvious check would be

              serialverid -classpath jbossmq.jar -show org.jboss.mq.Connection
              or one of the other classes in org.jboss.mq
