Daniel,
You are on the right track. Sorry, I should have mentioned this before. The
classes from which @Scope annotations are processed in implementation.osgi
should be listed under the attribute "classes" in <implementation.osgi/> in
the composite file.
<implementation.osgi
xmlns=http://tuscany.apache.org/xmlns/sca/1.0bundleSymbolicName="gamma";
classes="services.GammaImpl"/>
There are some examples which use servicefactory in
itest/osgi-implementation (eg. factory-ds-test.composite). Most annotations
like @Property are processed from the implementation class of the service
(GammaImpl) once the service instance is obtained, even if the class is not
listed in <implementation.osgi/>. But since scope needs to be determined
before the service instance is obtained from OSGi, the class(es) from which
@Scope annotation is processed should be listed in the composite file.
