Sounds like you didn't run the rmic compiler to generate stubs and skeletons.
It's been so long since I've done raw RMI by hand that I don't know if that step is still required. But it was the last time I did RMI.
If you did run rmic, then I'd guess that you didn't package the stub and skeleton properly with the server and client sides. If you can find those .class files, check your packaging and deployment.
