Your value objects wouldn't by some strange chance be EJB entity objects, or
remote implementation objects, would they? How about a code snippet of your
Value object definition, and the method which returns the value object to
the client, and the client code which tries to access the value object.

I was using "Collection". I just tried changing to "ArrayList", and it had
no
effect.
Note that I appear to have no problem getting the object of the collection
class, either "Collection" or "ArrayList", but when I try to pull an object
out
of the collection, it is of type "$Proxy2", and not my value object class.
Also note that my value object class implements Serializable.
