    Problem looking with CastClassException on JBossConnectionFa

    Karen Kramer Newbie

      Using JBoss EAP 3.4.0 with JBossMessaging 1.4.0.SP3
      We are migrating from JBoss 4.2.2 GA with JBossMQ

      I was able to download the example client code for a basic send/receive with a queue....the client runs perfectly:

      Here is remote client code which I could run and results up to getting the Session object :

      public void setupPTP()
      throws JMSException,
      NamingException
      {

      Hashtable env = new Hashtable();

      env.put( Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory" );
      env.put( Context.PROVIDER_URL, "localhost:1099" );
      env.put( Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );

      InitialContext iniCtx = new InitialContext(env);

      System.out.println("Here 1");
      Object tmp = iniCtx.lookup("ConnectionFactory");
      System.out.println("Got the tmp object: tmp is " + tmp.toString());
      QueueConnectionFactory qcf = (QueueConnectionFactory) tmp;
      System.out.println("Got the QueueConnectionFactory: + qcf is " + qcf.toString());

      conn = qcf.createQueueConnection();
      System.out.println("Got the QueueConnection: conn is " + conn.toString());
      que = (Queue) iniCtx.lookup("queue/EventSubmitServiceCommandQueue");
      System.out.println("Got the Que: que is " + que.toString());
      session = conn.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);
      System.out.println("Got the Session: session is " + session.toString());
      conn.start();
      }

      RESULTS: THIS IS GOOD!

      Got the tmp object: tmp is JBossConnectionFactory->ConnectionFactoryDelegate[jboss.messaging.connectionfactory:service=ConnectionFactory, SID=0]
      Got the QueueConnectionFactory: + qcf is JBossConnectionFactory->ConnectionFactoryDelegate[jboss.messaging.connectionfactory:service=ConnectionFactory, SID=0]
      Got the QueueConnection: conn is JBossConnection->ConnectionDelegate[13994297, ID=36-6udisckf-1-1a66ockf-7c3hoj-l1jvs4, SID=0]
      Got the Que: que is JBossQueue[EventSubmitServiceCommandQueue]
      Got the Session: session is JBossSession->SessionDelegate[18012736, ID=46-zxdisckf-1-1a66ockf-7c3hoj-l1jvs4]

      PROBLEM
      OK, so now I paste the same exact code into a java class inside of our application and I am getting a ClassCastException in the line:

      QueueConnectionFactory qcf = ( QueueConnectionFactory ) tmp;

      tmp is an instance of JBossConnectionFactory which (when I checked the source noticed) implements QueueConnectionFactory...so why won't it cast?

      Does this have to do with the JNDI tree? Here is mine(part)

      I've searched on the net and it doesn't appear to be a problem for anyone else, so I figured I was doing something ignorant...any help?
