We have a serious problem when performing a lookup to a JNDI lookup on a TopicConnectionFactory resource defined as a WASTopicConnectionFactory using MQ Simulator for JAVA developers. There is a class cast exception from com.ibm.ejs.jms.JMSTopicConnectionFactoryHandle to the
javax.jms.TopicConnectionFactory. However as far as I can tell these 2 items should be compatible. Any pointers?

We have tried all the usual suspects - delete the definitions and redo them.

Cheers in advance,

P

Dunno if this helps explain the problem... but on further investigation it emerges that a ClassCastException occurs on any resource jndo lookup. This implies that Websphere is not finding the class definitions for these objects at runtime BUT... I can't figure out where this should be set?

It is sorta covered in the JavaRanch Style Guide.
