Thanks Jim.

I didn't notice the support classes in common. I will have a look at it
today.

Jim Marino commented on TUSCANY-329:
------------------------------------

Hi Meeraj,

The doc on this is still lacking but did you notice the support classes
in extensions under core? These handle many of the "common" cases? Also,
I'm currently doing some work in the sandbox on simplifying the
extension API further some your feedback on improvements to the
extisting API (it's still very rough) would be great to hear.

Thanks,
Jim

> The work to create simple APIs for adding extensions has made some  of
the work required to add an extension much simpler, but there's still
things that can be simplfied further for container extensions for new
component types. The relevant classes are the ContextFactory,
ComponentContext, and TargetInvoker which have a non trivial amount of
code and its virtually identical for most simple components.  A
ComponentTargetInvoker would also be almost identical to the
o.a.t.c.extension.ExternalServiceTargetInvoker. Code for these classes
already exists in the Java container, it just needs to be refactored a
little to be generic and moved to the o.a.t.c.extension package.
> Be really great if we could get this done before M1 so we have stable
extension APIs for people to work with.
