There is some brainstorming going on at mobicents-public google group, with respect to Sbb configuration means. Click here to read or participate.
Anyway I think we could go beyond the proposed changes and for instance support annotations (as alternative to xml descriptor parts) or replace the usage of JNDI with a richer SbbContext, but I'm really interested in your point of view, so let us know what you don't like in the current revision of JAIN SLEE and how would you fix it.
