Detailed Description

This example shows how to setup a simple client subscribing to a topic. This code shows how to get a Subscriber instance :

   try {
     s = PubSubFactory.subscriber();
   } catch (MOMException me) {
     System.out.println("MOMException raised while instantiating a Subscriber");
     me.printStackTrace();
   }

And this shows how to implement the onMessage() method for a SubscriptionListener:

 public void onMessage(javax.jms.Message message) {
 // Subscriber implementation of the listener
   try {
     javax.jms.TextMessage msg = (javax.jms.TextMessage)message;
     System.out.println("Got message  : " + msg.getText());
     if (msg.getText().equals("bye")) {
       System.out.println("Time to close!");
       s.unSubscribe(subscriptionToken);
       s.close();
     }
   } catch(javax.jms.JMSException je) {
     System.out.println("JMSException raised while processing message: "+message);
     je.printStackTrace();
   }
 }
