Writing a Message Listener

The JMS MessageListener interface has a single method onMessage(Message).

A simple message application can implement that message listener waiting to receive messages from the queue.

MyListener.java

import javax.jms.*;

public class MyListener implements MessageListener {
  public void onMessage(Message message)
  {
     TextMessage text = (TextMessage) message;

     System.out.println("Message: " + text.getText());
  }
}

Configuring a Listener Resource

<resource type="com.caucho.jms.resource.ListenerResource">
  <init>
     <connection-factory>${jmsFactory}</connection-factory>

     <destination>${queue}</destination>

     <listener type="example.MyListener"/>
 </init>
</resource>
