    java.lang.ClassNotFoundException: org.jboss.mq.referenceable

      Hello:

      I had posted an earlier message but I have moved beyond that after much headache... Here is my latest problem... Any help would be great.

      testTopicException: javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
      java.lang.ClassNotFoundException: org.jboss.mq.referenceable.ObjectRefAddr (no security manager: RMI class loader disabled)]
      java.lang.NullPointerException
      at com.message.TopicSendClient.sendMessage(TopicSendClient.java:62)
      at com.message.TopicSendClient.main(TopicSendClient.java:19)
      Exception in thread "main"

      -----------------------------------------------------------------------------------

      Following is my class code

      package com.message;

      import java.util.Hashtable;
      import javax.jms.*;
      import javax.naming.*;

      // Topic client that sends message on a topic
      public class TopicSendClient {

      TopicConnection conn = null;
      TopicSession session = null;
      Topic topic = null;

      // Main Method
      public static void main(String[] args) {
      System.out.println("Starting the topic publisher client");

      TopicSendClient client = new TopicSendClient();
      client.sendMessage("This is test message sent at: " + System.currentTimeMillis());
      try {
      client.stop();
      } catch (JMSException e) {
      System.out.println("Exception: " + e);
      }

      System.out.println("Stopping the topic publisher client");
      System.exit(0);
      }

      // METHOD setupPubSub
      public void setupPubSub() throws JMSException, NamingException {

      Hashtable env = new Hashtable();
      env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
      env.put(Context.PROVIDER_URL, "hp:1099/");

      InitialContext intCtx = new InitialContext(env);
      Object obj = intCtx.lookup("ConnectionFactory");

      TopicConnectionFactory tcf = (TopicConnectionFactory)obj;
      conn = tcf.createTopicConnection();

      topic = (Topic)intCtx.lookup("aliTopic");
      session = conn.createTopicSession(false, TopicSession.AUTO_ACKNOWLEDGE);

      conn.start();
      }

      // METHID sendMessage
      public void sendMessage(String text) {
      System.out.print("Getting ready to send message on topic: aliTopic");

      try {
      setupPubSub();
      } catch (JMSException e) {
      System.out.println("Exception: " + e);
      } catch (NamingException e) {
      System.out.println("Exception: " + e);
      }

      try {
      TopicPublisher topicPub = session.createPublisher(topic);
      TextMessage msg = session.createTextMessage(text);

      topicPub.publish(msg);
      System.out.print("Sent message: " + "'" + msg.getText() + ", " + "on topic: aliTopic");
      topicPub.close();
      } catch (JMSException e) {
      System.out.println("Exception: " + e);
      }

      System.out.println("Ending the TopicSendClient job!");
      }

      // METHOD stop
      public void stop() throws JMSException {
      conn.stop();
      session.close();
      conn.close();
      }
      }
