Jarek Gawor commented on GERONIMO-3793:
---------------------------------------
I can replicate this problem with 2.0.3-SNAPSHOT but not 2.1-SNAPSHOT.
After a little debugging it looks like the something (maybe in OpenEJB) is
changing the ClassLoader that is associated with the current thread of
execution. And since the classloader gets changed to some other classloader,
JAXB is unable to load/find the classes in the ejb jar file causing these
exceptions.

> From what I understand, the return type should be added to the JaxB context
> automatically.
> Just to make sure I wasn't doing something wrong in my Customer class, I
> added another method to my bean that returned a java.util.List of Strings.
> When calling this method, I also got the same sort of error:
