rmi Server ClassNotFoundException problems

[schwarcz]

I'm trying to resurrect some of my old RMI code and running into problems
where the bind() throws a ClassNotFoundException for the remote interface.
The old code ran on a older JDK and an older version of Windows.

Any help you could offer would be GREATLY appreciated.

I'm running on Windows XP Pro with 5.0 of the JDK. I've done my best to turn
off any firewall, ani-virus, and Internet worm (Norton) checking.

I've tried to reduce it a trivial case:
* Message: an interface that extends Remote
* MessageImpl: a class that implements Message and extends
UnicatseRemoteObject.
* MessageServer: a class with a main method that:
a) creates an instance of MessageImpl
b) does a bind passing a name and the above instance.

All this is compiled and in a single jar.
I start the rmiregistry and run the Server.
However, I still get:

java.rmi.UnmarshalException: error unmarshalling arguments; nested exception
is:
java.lang.ClassNotFoundException: Message
at sun.rmi.server.UnicastServerRef.oldDispatch(Unicas tServerRef.java:385)
