My TestProject depends on the TuscanySDO Project .Currently The Test Project has a src/main/resources directory on class path(I manually created this directory)And also as you have suggested the TuscanySDO Project has TuscanySDO/impl/src/main/resources on its classpath.This folder contains the META-INF and HelperProvider info. So basically I have put HelperProvierImpl info at all possible places.But it just does not seem to be getting picked up.

It may be easier to just configure that as part of your "source".
