Can the same Java Bean consume from Queues or Topics? Only activemq.xml config change?

[BenXS <bx...@yahoo.co.uk>]

Assume I created successfully a Java Bean which consumes JMS msgs through an
onMessage() method from a queue.

Broker URL and queue name is defined in (Spring) XML in activemq.xml

Can I use the same (unchanged) java bean to consume jms msgs from a(nother)
topic instead from the previous queue?

As far as I can see I have simply to change the Sping XML declarations in
activemq.xml and to restart ActiveMQ. The Java Bean will listen then on a
topic.

Is this correct?

Otherwise: What must be changed in bean to switch from Queue to Topic
listening?

Yes, this should work.

You only have to be aware of the changed semantics and delivery guarantees.
