AFAIK you can't use OSGi declarative services from inside webapps or any deployent artifacts. Declarative services are only for other OSGi bundles. Its true that you can instantiate the service class and use it, or use PriviledgedCarbonContext.getOSGiService(), but they are not the same as using declarative services. If your service bundle leaves the OSGi environment then you are left with a stale reference. It is not true dynamic linking.
AFAIK there is no alternative for this currently so you have to use one of the two above approaches. Its still good to expose it as a OSGi service for future usage of it. Thanks, Johann.
