I think the following issue is the same as the problem you are encountering: -
http://jira.jboss.com/jira/browse/JBAS-1442
Can you try your code that reproduces the problem on JBoss 4.0.2 RC1.
Darranl,
Thanks a lot for your time taken to respond to me. Sounds like exactly my problem (JBAS-1495). I will look into it to see if JBoss suplied a fix for this or not. I just wanted to thank you for you kind responses.
Cheers,
Art.
Just an update: the problem seems to be solved in JBoss 4.0.2 RC1.
