I'm guessing a class loader issue, but not sure how to fix it.
Suggestions?
Maybe try using the Jar Service Provider mechanism for XML to control
what parsers you're using?
http://java.sun.com/j2se/1.5.0/docs/guide/jar/jar.html#Service%20Provider
I've not used JBoss for a long time, so I can't make specific
suggestions on how to configure that so that it prefers one
classloader over another.
Cheers,
James
Thanks for the reply James! I'll check out the pointer you provided.
I'm hopeful that someone may have already solved this issue and can
provide their configuration.
