I have a JMS Queue in My jboss.

Now from my standalone Java class I send message (in the XML format )to the queue.

as queue is used for P2P communication.So there should be a dedicated listener to that queue to get the message.

If I have more than 2 listeners to that Queue, Can It be possible to send the message to a particular Listener Based on the Message Content?

Have you tried message selectors?

yes I tried it and able to solve it.


Code sample : message to queue.
--------------------------------
try {
Context ctx = new InitialContext(env);

/* ctx = new InitialContext(); */
cf = (QueueConnectionFactory) ctx.lookup("/ConnectionFactory");
destination = (Queue) ctx.lookup("queue/testQueue");
connection = cf.createQueueConnection();
session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
sender = session.createSender(destination);
message = session.createTextMessage();

String name ="shankha1";

message.setText("Hello World --- --- --- "+name);
//message.setJMSType("COMMUNICATOT");

message.setStringProperty("COMMUNICATOR",name);
System.out.println("Sending Message.");
sender.send(message);

connection.close();
System.out.println("Done.");
}
catch (NamingException e) {

e.printStackTrace();
}

catch (JMSException e) {

e.printStackTrace();
}

Code sample : Queue to message
-------------------------------
Context ctx = new InitialContext(env);
cf = (QueueConnectionFactory) ctx.lookup("/ConnectionFactory");
destination = (Queue) ctx.lookup("queue/testQueue");

connection = cf.createQueueConnection();
session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
connection.start();
//String selector = "to = '" + System.getProperty("user.name") + "'";

String selector="COMMUNICATOR='shankha1'";
receiver = session.createReceiver(destination,selector);

System.out.println("Waiting For A Message. QueueToMessage ");
//connection.start();
message = (TextMessage) receiver.receive();
 
It is sorta covered in the JavaRanch Style Guide.
