Hello all,
I have a small problem in my first JMS client program. I have installed a fresh and
clean JBoss 3.2.4 server, and without any further configuration, tried a little
program, that is posted next.
Can anybody please tell me why do i always get a null reference on
context.lookup("ConnectionFactory") instruction ?
I notice that ConnectionFactory appears on the JNDI object list of the Jmx Console.
Regards
Pedro F.

queueFactory = (QueueConnectionFactory)factory;
queueConnection = queueFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
queueSender = queueSession.createSender(queue);
TextMessage message = queueSession.createTextMessage();
message.setText(sCommand);
queueSender.send(queue, message);
queueSession.close();
queueConnection.close();
