Subject: Re: [wsrp] [WSRP-IMPL] Thoughts on WSRP Open Source Implementatation...


It's a more general implementation. The WSRP-JSR168 bridge is just one
case.

Is the Apache effort intended to deliver *just*
a JSR 168 Container exposing WSRP "services", or
is it a broader effort to implement WSIA & WSRP?

Sorry if I am asking an obvious question, I'm just
getting myself involved in the above so I am catching
up.
