receiveNoWait returns always null

[kcp]

Hi,

I have a problem when I try to consume message from a queue using the method "receiveNoWait".

I have an MBean which uses a QueueBrowser to determine a set of message IDs that should be processed. After the selection a message selector is used to retrieve the message from the queue (the selector uses the property "JMSMessageID").

When I call "receiveNoWait" on the receiver, it always returns null. If I use the blocking receive call (either with or without setting a timeout), it works and I get the message.

I use JBoss 4.2.2 with JBossMessaging 1.4.0.SP3 and a Mysql5 as JMS persistence.

Any ideas?

Regards
Charly
