The following code example illustrates how you set a connection event listener. Whenever a connection event occurs, the event listener's onEvent method will be invoked by the client runtime.
//create an MQ connection factory. com.sun.messaging.ConnectionFactory factory = new com.sun.messaging.ConnectionFactory(); //create an MQ connection. com.sun.messaging.jms.Connection connection = (com.sun.messaging.jms.Connection )factory.createConnection(); //construct an MQ event listener. The listener implements //com.sun.messaging.jms.notification.EventListener interface. com.sun.messaging.jms.notification.EventListener eListener = new ApplicationEventListener(); //set event listener to the MQ connection. connection.setEventListener ( eListener );
