Using JMS in a session bean 2004-10-15 - By Tong Wang
Back I believe it is because of transaction. Before the method finishes and transaction committed, the message you send is not in the queue ready to be received, thus response will never come back until you commit the transaction.

Hello,
Please would you know if I can send a message and then receive a response message in one method from stateless session bean. Seems to me that the messages that the bean is sending are placed on the queue when the execution of the bean method is finished thus it can never receive the response. If it is so how can that be resolved. Any pattern .. ? The code below works fine in a servlet but in a session bean it always timeouts. I am using Embeded messaging in WebSphere and there is a plain Java receiver of messages from the bean and it is sending responses back.
Thank you, John
sessionBeanMethod() { .... .... connection = factory.createQueueConnection(); QueueSession session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE); QueueSender sender = session.createSender(requestQueue); QueueReceiver receiver = session.createReceiver(responseQueue, selector); connection.start(); TextMessage requestMessage = session.createTextMessage("message"); requestMessage.setJMSCorrelationID(messageID); sender.send(requestMessage); Message responseMessage = receiver.receive(5000); .... }
