Where do yo get the server from? I didn't mention it and the others not either. Sure the running implementation of the service is not needed to be locally available, there was never a question regarding this. Why must we ensure that the injected Service may be no ServiceComposite? If it is a ServiceComposite with a remote proxy Mixin in the current Module configuration this is perfectly ok, the qi4j application on the server then has the Mixin which actually implements the service and exports it that the proxy can access it ?
Or do I get sth wrong?
