    Critical error in createSubscriber JBoss 3 JMS

    Jordan Zommick Newbie

      We've just moved into production with JBoss after developing for a year and have found a critical error inside of JBoss that I am hoping someone has a workaround. The following code works great inside a local area network; however, it locks up the client AND worse jboss when a user tries to connect from the internet through firewall. The firewall is completely open for all ports for the ip address. I have put print statements in my code and have determined that it hangs on the createSubscriber(topic) call below. Essentially, I am sending a message round trip so I need a publisher and subscriber. A call to createSubscriber subsequently locks the client and the JBoss server. I am using the latest 3.0 release with tomcat. Is this a bug that has been fixed (hopefully can get a patch) or am I missing something in the jms xml configuration that is non standard? I am creating temporary topics through mbean and the topic already exist. As I said before, internally, everything works great. HELP!!!

      private void initializeTopicConnection() {
      InitialContext jndiContext = null;
      try {
      jndiContext = new InitialContext();
      JComboBox cb = getPortGroupComboBox();
      String selectedObject = (String) cb.getSelectedItem();
      TopicConnectionFactory topicFactory =
      (TopicConnectionFactory) jndiContext.lookup("ConnectionFactory");
      Topic topic = (Topic) jndiContext.lookup("topic/"+selectedObject);
      topicConnection = topicFactory.createTopicConnection();
      topicSession = topicConnection.createTopicSession(
      // No transaction
      // Auto ack
      publisher = topicSession.createPublisher(topic);
      TopicSubscriber subscriber = topicSession.createSubscriber(topic);
      } catch (Exception e) {
      System.out.println("Failed to initialize Topic Connection: " + e.toString());
      } finally {
      try {
      if (jndiContext != null) {
      } catch (Exception e) {
