    EJB 3.0 doesn't work with isolated classloaders....

    iwadasn Newbie


      IF you set the classloader isolation to true (see here: http://docs.jboss.org/jbossas/jboss4guide/r3/html/pr05.html) EJB 3.0 doesn't appear to work. Here's the sort of exceptions you can expect to get....

      I can send in this .ear that shows this property, if you like....

      It would be simpler to just look at your "package" tutorial, as the isolation breaks that too.

      Happy Hunting,
