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?

P

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,

Any help greatly appreciated as I'm well and truly stumped!

P

I've got the same problem! Wondered if anyone had figured out the solution (ok this was an old post)

I have WSAD 5.1.2 installed on my pc and I'm trying to use embedded messaging to communiacate with my test server... I installed the embedded messaging client and server direct from the cd and it's not working. I've deinstalled and reinstalled the embedded messaging but it's made zero difference.... Any clues?

I'll give 'Thinking in Java' a shout then. Certainly won't do any harm to brush up on my basic Java skills in the process.

P.S. Any clues on a good Patterns in Java book?

I completed the JAVA programmer cert and recently completed the BCD cert as well.

Currently I do use JAVA in my work and I'm not bad at fixing problems but I'm increasingly frustrated that I can't think OO in terms of new code writing. I think I need a readable book that helps me apply the basic coding structures and directs me on how to use the base classes as well as how to use those important design patterns.

I have read:
JAVA 2 (1.3 edition) (Ivor Horton) - but found it overly detailed - more suitable as reference manual
Sun Certified Programmer & Developer for JAVA 2 Study Guide (Kathy Sierra, Bert Bates) - great for passing exam but not very 'real life' - very readable
Head First EJB - Again excellent for passing exam but also short on 'real life' - very readable

Anyone got any clues?

Cheers in advance

Gotta disagree.
The only way a stateful session bean can be removed:
1) Call ejbRemove
2) Timeout
3) system crash
The bean can only call ejbRemove on a 'method ready' bean.
The container will therefore call ejbActivate() and then ejbRemove() to perform the request.
