[JBossMQ] - MDB sending messages
by MarcusDidiusFalco
Hallo I am experimenting with a MDB which should also be able to send back a message.
On JBoss 4.2.2.GA out of the box.

|

| .createQueueConnection();
| this.queueSession = queueConnection.createQueueSession(false,

| queueConnection.start();
|
|
| } catch (JMSException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| }
|
| public void onMessage(Message message) {
| log.info("Server onMessage");
| if (message instanceof TextMessage) {
| TextMessage textMessage = (TextMessage) message;
| try {
| log.info(textMessage.getText());
| QueueSender queueSender = queueSession.createSender(responseQueue);
| TextMessage responseTextMessage = this.queueSession.createTextMessage("foobar");
| queueSender.send(responseTextMessage);
| } catch (JMSException e) {
| log.error(e);
| }
| }
|
| }
|
| @PreDestroy
| public void destroy() {
|
| }
|
| }

When this MDB receives a message following exception is thrown

I had also tried looking up the QueueConnectionFactory and the queue.
For the queue I had received a NameNotFoundException. Although the queue is clearly bound.
| +- queue (class: org.jnp.interfaces.NamingContext)
| | +- D (class: org.jboss.mq.SpyQueue)
| .....
| | +- BafoegQueue (class: org.jboss.mq.SpyQueue)
| | +- BafoegRepsonseQueue (class: org.jboss.mq.SpyQueue)
|
I have both tried "queue/BafoegRepsonseQueue"
and "BafoegRepsonseQueue".
Can anybody help me with this?
Thanks,
Hans
