No, JMS specification does not include something like timed message processing. Therefore every solution to you problem is application server specificin a way.
You have two basisc alternatives for JBOSS:
1) use the newly introduced scheduled message delivery feature that will be available in JBoss 3.2.2. At the moment, the scheduled delivery has to be initiated by the message sender, so this solution is not really well suited for you problem.
2) use the JBoss specific scheduler service for timed invocation of a user defined class that handles message processing. In your case you could setup an invocation e.g. every 1 minute or so and check current time against you processing time slot. If the invocation i within you time slot that create a normal jms destination receiver within your user class and process all so far queued messages.. not very

There are no methods in the queue/topic interface for that purpose (e.g. start/stop delivery) so far. JMS specification does not define such a behaviour.

Hi there
I want to process JMS Messages in a given time slot.
Scenario:
Multiple clients send messages to a certain JMS topic/queue. The messages
must be delivered at a certain time. The posting client is usually unaware
of this time.
How can I configure such a behaviour?
Is there a right way to do this within JMS?
I thought about the JBoss TimerService to start and stop the delivering of
messages to achieve time slot behaviour. I can't find any method in the
Queue/Topic Management Interface.
