[JBoss-user] NullPointerException while trying to obtain JMS TopicConnectionFactory on 2.4.6

[McLain, Mark - Apogent]

I have written the following test method in a JUnit 3.7 TestCase:       public void testSendMessageToProcessor()             throws NamingException, JMSException     {         Context ctx = new InitialContext();         TopicConnectionFactory factory =                 (TopicConnectionFactory) ctx.lookup("TopicConnectionFactory");     --> TopicConnection connection = factory.createTopicConnection();         TopicSession session = connection.createTopicSession(false,                                                              Session.AUTO_ACKNOWLEDGE);         Topic topic = (Topic) ctx.lookup("topic/testTopic");         TopicPublisher sender = session.createPublisher(topic);         TextMessage message = session.createTextMessage();         message.setText("This is only a test");         sender.publish(message);         if(connection != null)         {             connection.close();         }     }   This method executed successfully on JBoss 2.4.4.  On JBoss 2.4.6, however, it fails with a NullPointerException at the line indicated by the arrow.  I have verified via JNDIView that TopicConnectionFactory is available; I have also verified that topic/testTopic is available, should the method execute beyond where it has thus far.  I would greatly appreciate any help, as neither I nor my colleagues have been able to spot any flaws in the code or the configuration.  I'm running J2SDK 1.3.1_03 on Windows XP Pro.   Thank you very much for your time.
