1. Re: $Proxy1.create(Unknown Source) java.lang.NullPointerExce

I need to solve this problem, so I looked even deeper into it. The class LocalHomeProxy that create the exception call invoke on a factory. This factory is passed to LocalHomeProxy as a parameter of the constructor. I obviously didn't pass anything to the constructor so the NullPointerException. Does anyone knows how LocalHomeProxy is called and what I can set up to have the factory not being null.
thanks in advance,
Alex
