Hi,
We had a debate on this topic. See:
http://osdir.com/ml/dev-tuscany.apache.org/2010-06/msg00164.html
And apparently, we didn't reach agreement.
It's probably a good idea to restart that discussion and find a
consensus on this. After having not looked at the Tuscany code for a
while I must admit I was a little confused by the multiple Node types.
I'll try to participate in the discussion as much as I can, although I
have little spare time these days. In the meantime, I'd like to continue
to use the mainstream Node implementation for some time in
samples/launcher-shell, as it's what's working with webapps, all the
test cases, samples etc.
I think it would be a good idea to agree on the commands for shell. This will
help us understand how users use SCA. Then it can be translated into a set of
API/SPIs. Mixing different steps into one layer could prevent us from seeing
the complete user story.
And like I tried to say in another email in this thread, I think we
should distinguish:
- Domain management, assembling components in a domain;
and
- Runtime instance configuration and management, loading a contribution
in a runtime instance and starting/stopping it.
They are really different IMHO, for example an SCA domain administrator
can spend a day assembling components in a domain before starting a
single runtime instance, and stopping a server doesn't mean that he's
removing a composite from the SCA domain...
