Re: Methods to EventForwardingFactory

Hi Christian,

You are not holding me up. I have already implemented this as my own 
factory bcoz I need to be deriving from my own listener factories for 
other reasons. And it works really well. Now I dont have to specify them 
in my Gateways just for forwarding.

I am interested in knowing more about the object repository. Not 
currently using it. Can you point me to any documentation and its proper 
use?
Thanks,
Srini.
