Hi Meeraj,
It's good to see we didn't scare you off quite yet ;-) Comments inline.

Hi,
I have been away from the list for a few weeks. I am back on now
looking
at things in general.
Before I disappeared, I was looking at the Groovy container and spaces
binding. I would like to continue working on them.
Great
I think Jim has
refactored the Groovy container in the sandbox to fit in with the new
extension model. Should all the new extensions (containers, bindings
etc) be written according to the extension model (I am assuming the
new
extension model is still in the sandbox).
As some background, we currently have two proposals on the table for
moving forward (you're welcome to add a third if you have ideas):
1. Move the sandbox code ("core2") to trunk (or even a branch) and
take that as a basis for moving forward. The sandbox code
incorporates some things from M1 but is a very significant refactor
to better accomodate changes to the SCA spec and issues we
encountered with M1. As part of this move, we would refactor for
modularity and simplification where appropriate.
A set of overview slides on the spec changes as well as core2 can be
found here:
http://svn.apache.org/viewvc/incubator/tuscany/sandbox/jboynes/sca/doc/
2. Start afresh and merge pieces of M1 and core2 one step at a time
according to a set of use cases, starting with simple ones first
(e.g. bootstrap a component)
I won't go into the pros and cons of each approach since there has
been a number of emails on the list related to those.
We already have quite a bit of work going on in core2 and some have
started to jump in with extensions to it (Spring, Celtix, the Groovy
container you donated, data transformation, conversational support
and callbacks, OSGi deployment, etc.). I'd be more than happy to
assist if you're interested. In terms of the technical status of
core2, we're still bringing up the end-to-end operation of the
runtime, which should not be too much longer (I've got it running on
my machine but need to clean up some code before checkin). All of the
major subsystems are in place and operational and we have one example
("eager init"), so it's a matter of connecting one more piece. We are
unfortunately sorely lacking in documentation so I'm willing to
provide as much direct assistance as you need if you would like to
work on core2.
We have started a scenarios page on the wiki so you may want to also
look at that as well as add to it with things you believe are
interesting and/or would like to work on:
http://wiki.apache.org/ws/Tuscany/TuscanyJava/Scenarios
Also, since we are in the process of gaining consensus, it would be
good if you had an opinion on either of the two approaches (or an
alternative)
I am also interested in
knowing whether anyone is working on asynchronous bindings?
I think that would be a really good thing to work on. Again, if you
would like to do it in core2, I'm more than happy to help. Perhaps
adding something to the wiki with your thoughts would be a good way
to start the process?
If you've made it to this point in the message, I hope you're not
scared off! It would be great to hear more of your input.
Jim
Many thanks
Meeraj
