Hi On the face of it it seems to be complaining about a miss-match in reference names. I.e. between MyService and myService. But as you say this is with Node B that's seems a bit odd. Looking at the implementation for the service does this make any sense? Can you post simplecallback.MyClientImpl and simplecallback.MyServiceImpl?
Under the covers we do create some automatic references and services, the names of which are based on the forward reference and service names, so something could be going wrong there. Regards Simon
