the easiest would be to add a startup service :
@Service
public class MyStartup implements Startup {
...
}
now if you don't need any GlassFish services, OSGi route is fine.

which service ? this service was added to OSGi service registry ?

I can see Sahoo helped you getting to the habitat, I believe you can
also try normal Java EE injection,
@Resource
Habitat habitat;
or even better, if your service was added to the habitat or as an OSGi
service then you do not need to depend on hk2 at all, you can just do
@Resource(mappedName="osgiName")
SomeService myService
look at my latest blog entry

it might help.
