Hi, I have the same problem trying to run it under starter. I have got the jobdone sub in the starter service, but I don't think that is the problem. It has something to do with the jrdc server. It finds a xxxxxxxx.main class and not a xxxxxxxx.starter class. This happens on the server before a response is sent back to the client. It bombs out on line 50 in the RDCHandler. Moving everything to the main activity sorts the problem out.
Update: If I create a "starter" code module on the server, and put the DBCommand declaration in it instead of "main" then it works. It looks like the DBCommand declaration in the server must match the client (in the same named code module)
