It's been a couple days and the odds are you've figured it out already, but 
since no one has responded I'll take the chance that it is still hanging.

You need to override the default classloading behavior for jboss, which 
essentially means you have to define a classloader for your ear.  Rather than 
cut and paste the whoel thing, here are a couple of links that explain it:

Check for the section isolation w/server override.
http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration

Here's one on Raible's site.  He hits so much of this kind of thing with app 
fuse, I've always found it's a good idea to search his entries early on in any 
sort of issue like this because he very often hits it early and is good about 
posting fixes and links to fixes.
