I've done a demo from the "Professional Java Server Programming (J2EE 1.3 
ed.)" book that works under the following
circumstances:

1) Client on W2K, Server on W2K - works fine
2) Client on Linux, Server on Linux - works fine
3) Client on Linux, Server on W2K - works fine

But it fails with the client on W2K and server on Linux.  Here's the
exception:

java.rmi.NoSuchObjectException: activatable object no longer registered
        at sun.rmi.server.ActivatableRef.activate(Unknown Source)
        at sun.rmi.server.ActivatableRef.invoke(Unknown Source)
        at HelloServer_Stub.sayHello(Unknown Source)
        at HelloClient.main(HelloClient.java:19)

Any thoughts?
