[jboss-dev] Re: ServiceBindingManager status?

[Brian Stansberry]

That sounds like my #2. Or are you saying load the whole unrefactored 
thing from the deployers dir, but via a -service.xml? Possible but don't 
know if that would cause issues.

I can spend a couple hours today/tomorrow experimenting with the wrapper 
concept, and maybe simply deploying via service.xml. But I don't want to 
waste effort unless there's agreement that getting SBM to work for Beta4 
is an important goal.  And if there's consensus (e.g. from Remy) that 
whatever I'm trying is an acceptable temporary measure if it works.
