Just to be on the same page I installed eclipse-ipojo-plugin too. First finding : you don't need a bogus component. You can just type <ipojo> <component/> </ipojo>
inside you metadata.xml and it'll pass silently.

Could you share me your MANIFEST for the final state(bogus metadata.xml + annotations)? On Fri, Oct 12, 2012 at 5:05 AM, Cook, Michael J.
