Subject Re: Trouble with aggregating definitions.xml in distro
Date Sat, 01 Mar 2008 07:35:22 GMT
Hi Sebastien,

Yes, I will try the scenarios you have mentioned and see if things work fine
with the transformer.

Please see my comments inline for the discussion specific to this thread.

I suppose that's the way it is right now.  The definitions.xml is processed
as any other artifact in a contribution and can be anywhere.

Its only for the definitions.xml file we are packaging in the tuscany
modules - as part of the runtime do we have the issue of placing them in a
well know place.  This is because these definitions.xml  1) don't get to be
treated as a contribution artifact 2) they need to be read before
contribution artifacts are read and resolved.  So to load them during the
runtime startup we are using the ServiceDiscovery to locate all
definitions.xml across Tuscany modules and the ServiceDiscovery needs to be
give a specific location.

I guess these attachments would get to be treated the same way as
definitions.xml in the sense, as any other artifact.
