Subject [Fwd: Re: GSoC Project - Tuscany SCA support in the Geronimo admin Console]
Date Tue, 01 Jul 2008 11:51:37 GMT
I'm resending this as I didn't see any responses to the
questions and discussion points that I posed.  Would anyone with
an interest in Tuscany/Geronimo integration like to join in this

As I understand it, there are different aspects to this project:

1. The visual integration of Tuscany/SCA admin into the Geronimo
    console, in a way that looks natural to the Geronimo user.

2. The ability to include Geronimo runtime componments (WARs,
    EJBs, etc.) in the Tuscany domain and administer them.

For each of these, there are two options:

1a. There is a browser-based admin console as part of the
     new workspace code.  It would be possible to repackage the
     visual presentation that this uses (HTML rendering) into a
     plugin within the Geronimo admin console.

1b. There are lower-level APIs into the new node/domain code that
     could be used to extract and manipulate the admin information
     and render it in the Geronimo console in a way that's more
     consistent with how the Geronimo console does things.

These options 1a and 1b should be evaluated so that we can
understand the difference between them and decide which approach
is best for the short term and for the long term.

2a. This could be based on the new domain code.  Currently there
     is not a clear understanding on how to integrate this with
     Geronimo components.  However, it can be used to administer
     non-Geronimo components.

2b. This could be based on the old domain code, which doesn't
     work with Geronimo currently.  We could get this integration
     working again, but it doesn't take us forward in the right

To decide between these pairs of options, the following questions
need to be answered:

What is the main focus of this project?  Is it 1 or 2?  If we
agree it's 1, and there is significant challenge and creativity
in doing that part, we could go with a less ambitious version
of 2, or vice versa.

How hard is it to do 1a/1b/2a/2b?  We should not combine a hard
flavour of 1 with a hard flavour of 2, as this would make the
project too difficult to accomplish in the time available.

Does 1b have significant value above 1a?

For the scope of the GSoC project, if we choose 2a, is it a
requirement that Geronimo-based components can be administered,
or is it OK as a first step to only be able to administer other
SCA components?

I have probably missed a few points.  Could others more familiar
than me with Geronimo please share their thoughts on the above,
and add anything else that I may have missed.
