Item (c) in my original posting can be resolved by moving namespace.jar from the directory jboss-root/lib to jboss-root/lib/endorsed
These problems were experienced while running J2SDK/JRE 1.4.2_05 from Sun.
Yes, I did find the Wiki last night some time after posting my original message.
Thank you for providing the samples - following those examples I did finally manage to get my bean working with Jboss.
However, I believe the issue with library locations is not addressed in the Wiki.
