Subject Re: Ability to set per-deployment gbeans?
Date Wed, 17 May 2006 00:28:19 GMT
Are we talking about Geronimo 1.0 or 1.1?  It will be quite easy to do
this in 1.1, but might be a bit more manual in 1.0.

Also, do I understand correctly that you have a single WAR with a
separate geronimo-web.xml for each customer?

Thanks,
