Let's assume that Bundle A defines a service interface and export the
package that contains it to OSGi:
Public interface ServiceInterface
{
.....
}
Bundle B, provides an OSGi component/service that implement the
service interface
@Component(immediate = true, metatype = true)
@Service(value = {ServiceInterface.class, ManagedService.class})
@org.apache.felix.scr.annotations.Properties({
@Property(name = Constants.SERVICE_PID, value =
"com.example.MyService"),
@Property(name = Constants.SERVICE_VENDOR, value = "Contoso"),
@Property(name = Constants.SERVICE_DESCRIPTION, value = "My Service"),
})
public class MyService implements ServiceInterface
{
...
}
Bundle C, contains Sling model classes that needs to use the above
service, we inject it using @Inject or @Inject @Source("osgi-service")
as per Sling Model documentation
@Model(adaptables = {Resource.class})
public class MyModel
{
@Inject
private ServiceInterface serviceInterface;
...
}
The problem is that the service never get injected into the model as
it should be, the Exception we get is thrown by the
ModelAdapterFactory saying that it's unable to inject MyService into
ServiceInterface as if they were an incompatible types but they are
not.
