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

[iwadasn]

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.
