That old CLASSPATH question again

[andyroo]

I am trying to run an example program and failing due to the following error ::

Trouble: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: simplermi.CalculatorImpl_Stub

Now I think this is a CLASSPATH problem and I have tried puting the directory with the classes in my CLASSPATH but it still does not work.

The JBuilder project is in

C:\Documents and Settings\Andy\jbproject\SimpleRMICalc

so I have put

C:\Documents and Settings\Andy\jbproject\SimpleRMICalc\classes

in my CLASSPATH setting and it still does not work - have I just got it completely wrong !!!

HELP PLEASE

Thanks

Andy
