I am in agreement with you that you should be able to just use #4
and #5in the list above. The castorJdoMbean.jar should probably be
the only thing that needs to reside in server/default/lib. I know
that JBoss is distributed with an older version of Castor in one
of the lib directories and that can just be removed. I may be wrong
(it's been a while since I've used JBoss/Castor), but I think that
the Castor jar can either be placed in the .ear/.war file or in
server/default/lib. Because you're using a .war and a .ear, it would
be a better idea to place it in server/default/lib because then
both archives can use it from there - no duplicate jars.
About the castorJdoMBean.jar, this is a JMX MBean that places the
Castor JDO instance in a JNDI ENC for you so that Castor is started
up with JBoss. IMO, I would use it rather than trying to worry about
putting the JDO instance in a JNDI ENC myself.
