ClassCastException using java:EJB provider

[__matthewHawthorne]

I'm using the java:EJB provider to deploy a stateless session bean as a 
web service.  The session bean is a facade to underlying entity beans. 
I have some code in place which converts the local entity references to 
value objects that are returned from the web service using the bean 
serializers and deserializers.

After adding some more beans to the tree today, I began getting a 
ClassCastException.  The code can execute flawlessly on the server side 
(invoking the method on the session bean directly).  However, when I 
attempt to invoke it via the web service I have problems.

It appears that Axis isn't finding what it expects at the provided jndi 
name.  But I've double-checked and the jndi name for the session bean is 
correct.  It doesn't appear that the method is being invoked at all. 
Any other ideas on what could be causing this?

Thanks!
