James,
We assume that the class is loaded when ActiveMQObjectMessage.getObject() is
called, and the de-serialization takes place. Is this correct? Now, after
looking at the code, it seems that the class loader is resolved in
ClassLoadingAwareObjectInputStream. Is this correct? What can cause it t
Thanks, Christopher,
No, it's not. The broker and the consumer are on two different machines. The
transport is TCP.
We use Jencks for the consumer.
We're currently on ActiveMQ 4.1, but we had this problem on 4.0 as well.

Hi -
I am using Spring 2.0 with ActiveMQ 4.1.1 (JDK6, Tomcat 5.5.x). I am
instantiating a broker using

As the (webapp) context loads, it aborts with the following error:

If you get a ClassCastException yet the object seems to be of the
correct class name, then it looks like a class loader issue (multiple
versions of the same class on the classpath). Otherwise if it was a
serialization issue, you wouldn't get an object you can inspect.

Active MQ also uses ports internally which are not configurable, these
ports are randomly allocated.

Is it possible to use a roundrobin policy in a rollback?
Currently a session.rollback results in retries on the same consumer. And if
they all fail, the message ends up on the Dead Letter Queue instead of
trying other available consumers. Does anyone have a solution?
