JBossMessaging has automatic failover.
If you want to control the failover the same style you would do on JBossMQ, you
need to disable failover and do the reconnects yourself.

Clebert,
Thanks for your input. I am fine to manually failover in my producer, as I
control that code.
However the problem I'm having is that, upon restarting a cluster node, the
MDBs do not 'wake up' and start consuming messages from the HA queue. The code
to connect the MDBs is controlled

Hmmm. From watching my logs, I think the reason the MDBs aren't 'waking up'

Whenever a @EJB is used, we internally add a micro container dependency on the
bean being injected. That way we ensure that the bean being injected is
available before the bean which uses the @EJB. With @IgnoreDependency, you can
override this behaviour so that the MC dependency is not created.

Thanks for helping out.
If I understand correctly, JBM 1.x load-balances at distribution time, not

Actually JBM 1.x does both. (BTW there is a FAQ on this, but I didn't right it

When using a clustered connection factory, subsequent *connections* will
normally be created to different nodes of the cluster, by default in a round
robin fashion.

The queue you created is a core queue.
The preferred way to create JMS destinations is using the JMSServerManagerImpl
on top of the MessagingServer you created:
| Configuration configuration = new ConfigurationImpl();
| configuration.setPersistenceEnabled(false);

When using the core API there i s no such thing as a topic, we only deal with
queues. Basically a topic consists of an address with multiple queues bound to
it where each queue will have a consumer(subscriber).
If you are using JMS then i would recommend taking a look at the

To clarify Jeff's answer a bit:
The MessagingServer you created is a core server. A core server knows nothing
about JMS - it's completely JMS agnostic, therefore it knows nothing about
topics.
This is discussed in the user manual:
