Summary: ClassCastException when using MDBs in Sun ONE AS7

Initial Comment:
I am running Sun ONE Application Server 7 with OpenJMS
as the JMS provider, and have run into a problem with
Message Driven Beans.

In the onMessage method of class
org.exolab.jms.client.JmsConnectionConsumer, a
ServerSession object is being retrieved from a server
session pool, and is then cast into a JmsServerSession
object. However, the server session pool is an
application server specific object (for Sun ONE AS7, it's
implemented by class
com.iplanet.ias.ejb.containers.IASServerSessionImpl),
and cannot necessarily be cast into an a
JmsServerSession object - a ClassCastException occurs
as a result. Unfortunately, Sun ONE does not allow me
to specify a different implementation of the
ServerSession interface.

Is there a workaround for the problem described? I need
to use Sun ONE AS7, and am curious if a similar problem
exists when using other application servers.

OpenJMS's support for MDB's is untested - if you have the
time, any contribution with respect to this would be much
appreciated.
