In this example, an application chooses to have its event listener log the connection event to the application's logging system:
public class ApplicationEventListener implements
				com.sun.messaging.jms.notification.EventListener {
public void onEvent ( com.sun.messaging.jms.notification.Event connEvent ) {
      	log (connEvent);
}
private void log ( com.sun.messaging.jms.notification.Event connEvent ) {
	      String eventCode = connEvent.getEventCode(); 
      	String eventMessage = connEvent.getEventMessage();
    	  //write event information to the output stream.
     	}
}
