Class Def Not Found for a stub when stub is already loaded

843793Apr 16 2003 — edited Apr 17 2003
I have programmed a rather elaborate RMI system (never having used RMI before at all). When I try to run the server, I get the following error:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: 
        java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: 
        java.lang.ClassNotFoundException: edu.foo.baz.distributed.PipelineNode_Stub

However, the stub class in question has already been loaded, as I can see when I run java with the -verbose option - the Stub has already been loaded (and the classloader went on to load many other classes), so why can't it find it? Is it looking for a different version??? I'm running on the macintosh 1.4.1_01, and my version of rmic supports the 1.1 rmi and the 1.2 rmi (I used the default 'compatibility' option).

I did run rmiregistry, and it's still running even as we speak.
