Maybe you have to define SecurityManager:

System.setSecurityManager(new SecurityManager());

Too small amount of data to find out solution.

The classpath problem? That's what this usually is. Client/Server/Registry all must be able to find your classes.

Hunter , can we discuss this problem on skype , it would easy then to identify it , as this unmarshalling problem has become really a headache for me now.
