RMI problem NoClassDefFoundError

[d]

I have recently extended my RMI interface to pass a new user defined object
between the client and server.

However I keep getting a java.lang.NoClassDefFoundError:
ipcshare.GenericPolicy error when I try to run my server. GenericPolicy
should be (and is) in ipcshare.jar

I would usually check the codebase but this is the same path as I use in the
compilation line, which works fine. The RMI interface also passes other
user defined objects from ipcshare.jar with out any problems. It is
GenericPolicy which is causing me the headaches.

TVM in advance

Complete error.
