Mark Combellack commented on TUSCANY-1487:
------------------------------------------
I am not sure of the best solution to this problem. Possible solutions include:
*) Update DefaultSCADomain to once again pass in a ModelResolver in step 4
above - i.e. roll out the change from SVN commit 558587
*) Update contributionService.contribute() method to allow passing in of an
Application Class Loader. This passed in Application class loader would then be
used to create the ExtensibleModelResolver in step 6
*) Update ContributionServiceImpl.addContribution() to use
Thread.currentThread().getContextClassLoader() rather than
getClass().getClassLoader() when constructing the ExtensibleModelResolver in
step 6
*) Some other inspired, cunning and clever solution thought of by the Tuscany
team :-)
Any thoughts/recommendations?
