Hi,

I have a WebStart downloaded Java SWING client that I want to have listen continuously to a server side Queue.

I am using a JBoss local server that has a Queue configured and bound to a JNDI name of "queue/goAdminOut".

I know that the queue exists and has a message waiting, because I can see it on the JBoss JMX web-console (see console screen print below).

Here is the relevant code.

1. Two classes that mimic my client.

TestConsumerView
-- A JFrame that stays alive till it is closed.

TestConsumer
-- An object that is instantiated as a field in TestConsumerView
-- It establishes the connection, session and message consumer with a selector. It also sets a Listener on the consumer.

2. The command screen print when I run TestConsumerView

3. A screen print from the JBoss JMX web console confirming that the message is in the queue.

TestConsumerView Code

SORRY! I mistakenly put two copies of TestConsumerView above and left out TestConsumer.

Here is the missing code:

Hi,
Are your send and receive operations in the same transactions? If yes, then the send and receive operations need to be separated out into 2 different transactions.

If they are already in different transaction, then try sending/receiving the message without the message selector, so that you can narrow down on the problem.
