Configuring MDB in WASv5 with WME6.5sp2

Hi,

I am trying to configure a simple MDB in WASv5 and using WME6.5-sp2 Broker.
My current setup throws an error:

[3/13/06 14:02:37:743 GMT] 5c86bff2 MDBListenerIm W WMSG0017E: Unable to lookup JMS resources, JNDI lookup exception: javax.naming.Reference
[3/13/06 14:02:37:789 GMT] 5c86bff2 MDBListenerIm W WMSG0019E: Unable to start MDB Listener TopicTestMessageDrivenBean, JMSDestination mdb/wme65/jms/RequestTopic : java.lang.ClassCastException: javax.naming.Reference

=

While the setup works fine with WME6.1-sp3-fp8.
I need to know whether there is a version issue between WAS and webMethods6.5.
Does webMethods6.5 Broker work with WAS v5?

Thanks
