    Thank you I can now run XEP inside of Jboss.

            I was wondering, I am getting some extremely slow processing times,
    in fact I am noticing that XEP takes at least 50% more time to render a 2
    page PDF document compared to FOP. I was wondering are there any performance
    tuning tips you may suggest ?

    The problem is due to incorrect class loader manipulations
    in JBoss: java.lang.String used by your application and java.lang.String
    used to load system properties are loaded by two different loaders, and
    appear as different classes. It causes problems for applications
    trying to enumerate system properties via java.util.Enumeration: you
    cannot cast obtained values to java.lang.String because the types
    don't match :-).

    The problem has been already addressed in XEP 3.5.4. I suggest
    upgrading XEP to the latest version.

    Best regards,
