The best way to process synchronous messages

[famousactress]

I'm trying to decide what the best way to process messages synchronously is. I understand that I can set up a session bean that does timed synchronous processing on a Queue much the same way a ServerSocket works. I was hoping I'd be able to use MDB's and 'push' the messages instead of pull them.

But for a given subscriber, I only want to dispatch one message at a time, and wait for the subscriber to finish processing that message until the next message is dispatched.

Thoughts? - Let me know if I'm not being clear.

// Send and wait for a reply
QueueRequestor queueRequestor = new QueueRequestor(session, queue);
TextMessage message = session.createTextMessage();
message.setText("Whatever");
TextMessage reply = (TextMessage) queueRequestor.request(message);

// Send the reply
Queue replyTo = (Queue) message.getJMSReplyTo();
QueueSender replySender = session.createSender(replyTo);
TextMessage reply = session.createTextMessage();
reply.setText("Whatever");
reply.setJMSCorrelationID(message.getJMSMessageID());
replySender.send(reply);
