I figured that the error would be with a ClassLoader, but I wasn't
sure which one. The fact that you're placing these jars in the
server/default/lib dir likely the issue here. The appropriate method
for using jars within a J2EE container (and even a web container)
is to place them within either the ear file (or the war file). The
reason for doing so is due to each application having it's own
context. Depending upon the level of isolation built into the
context, you may not have access to a jar from within an application
or vice versa - the app server's boot ClassLoader may not have
access to a jar if it's not in the correct location. So now I'm
curious to know how you're constructing your application and deploying
it in JBoss. Is it an ear or a war? Are you placing your other jars
within the WEB-INF/lib dir within the ear or war? Etc.
For the benefit of the entire Castor community, I'm also CC'ing the
castor-dev mailing list with this response. What's more, Patrick
may have some input here as his experience with the integration of
Castor and JBoss is more up to date than mine.
