Date Fri, 15 Sep 2006 22:37:25 GMT
Provide config/module aliasing ability
--------------------------------------

                 Key: GERONIMO-2409
                 URL: http://issues.apache.org/jira/browse/GERONIMO-2409
             Project: Geronimo
          Issue Type: Improvement
      Security Level: public (Regular issues)
          Components: core
    Affects Versions: 1.2
            Reporter: David Jencks
         Assigned To: David Jencks
             Fix For: 1.2


It's sort of impossible to swap a basic configuration such as transaction with a substitute
such as transaction-jta11: there are too many modules that depend on it that all have to be
rebuilt just because you changed one name.

To fix this we need some way to substitute one module (configuration) for another.  We might
aim for a function-based registry rather than a name based one, but that is more that I want
to think about right now.

I've done some simple experiments and it looks like some trivial changes in DefaultArtifactResolver,
the car maven plugin, and an additional properties file in the server at least let you swap
modules and get the server started.  I expected that changes in the kernel gbean lookups and
Configuration gbean lookups would be necessary as well, but I haven't needed them yet.

I think the changes so far should be applied since they clarify the explicit version resolution
code and enable at least some module swapping.  I suspect we'll find out soon if more work
is needed.
