Hello there,
is there a way to find out the contribution of a class at runtime?
The reason I ask:
That way, I could include versions of libraries that differ from the Tuscany
runtime by NOT putting them in the contribution itself, but in some
other place
over which I have full control (an “endorsed” directory or some such).
I would then load them using my own EndorsedLibrariesClassloader at
runtime, after Tuscany has already started up all my components.
This seems like an interesting approach. It could perhaps become part of
Tuscany if you're willing to contribute (no pun intended) the code.
Of course, that new classloader would need access to the current
contribution
in order to resolve imports etc.
If the new classloader is just loading external libraries, why does it
need to resolve imports via the contribution? Imports are only relevant
when you're loading contributions.

In fact, it would probably best to simply extend
org.apache.tuscany.sca.contribution.java.impl.ContributionClassLoader
(which would be the one containing the object that functions as the
client of
the library.)
However, ContributionClassLoader does not expose a public or protected
getter
for its private contribution field. Would I have to modify the source
(harmlessly,
in this case), or is there already some other API to find that contribution?
