I have never tried serializing an object by explicitly calling readObject()
and writeObject() on a serializable. Does that work?
Is there a reason why you were using the EJB handle? I'm pretty sure it's
no problem just to keep a reference to an entity bean, which will be
serialized by the container when your SSB is passivated. If you needed a
handle (which I beleive is mostely used if you need to store a long-term
reference outside the app server,) this should also be serialized for you
automatically.
Maybe I'm not understanding what you're trying to do?
