Subject Re: [Axis2] CHANGE : Components vs. Services?
Date Sat, 16 Jul 2005 15:17:55 GMT
Hi Glen;

I think the basic idea is to widen the scope of a componenet! and
replace service archive with a componenet archive. This allowed number
of services to share a same class loader.

mm .. seems ok to me (may be need to think bit more before commit my self :) ).
