Hi,
From whatever little I understand I would imagine that the config. info is
something that you will inject in as component properties. i.e. have a
property in the DAS ComponentType to inject the source of this config info
(could be a the config filename or a URL that you can open and read the
config...).
If this SCA Service abstraction of DAS is complete, maybe we must actually
think of projecting it distinctly outside the SCA & DAS infratructures - as
a component that is ready to use - i.e. can be pulled down and used in a
service assembly. Makes sense?

As for the naming :) I was just calling DAS exposed as an SCA service...

Yes, this was THE thing I know we need to improve as mentioned on this
thread :
http://www.mail-archive.com/tuscany-dev%40ws.apache.org/msg10421.html
SCA guys, any suggestions about something already available in SCA ? Or
maybe an Annotation ?

Could you elaborate little bit more here ? Why exactly this ?

Sure, it was just a setting in my eclipse IDE, I'll create a patch
removing
that.
As for the other things... I'll look into that and provide a patch with
the
changes...
