MDB's - Message Driven Beans

Einfache MDB:

@MessageDriven(activationConfig = {
   @ActivationConfigProperty(propertyName="destinationType",
      propertyValue="javax.jms.Queue"),
   @ActivationConfigProperty(propertyName="destination",
      propertyValue="queue/MyQueue")
})
public class MyJmsBean implements MessageListener {
   public void onMessage (Message msg) {
      // ...
   }
}

Senden einer Message an eine MDB:

try {
   InitialContext ctx = new InitialContext();
   queue = (Queue) ctx.lookup("queue/MyQueue");
   QueueConnectionFactory factory = (QueueConnectionFactory) ctx.lookup("ConnectionFactory");
   cnn = factory.createQueueConnection();
   sess = cnn.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);
} catch (Exception e) {
   e.printStackTrace ();
}
 
TextMessage msg = sess.createTextMessage(...);
 
sender = sess.createSender(queue);
sender.send(msg);
