ClassNotFound exception(stub) when running server

Question

Hi all,
I have written an RMI program. All fies are in same directory same package and same machine. When running the server it is giving ClassNotFoundException. Server is run from same directory as the files. I could run the implementation through its main method. What may be wrong with it. The registry is started from another DOS window(same machine) with CLASSPATH set to blank. I tried with setting classpath to the files directory. There is no security manager. This is full stack trace.
Hope anyone will help me and thanks in advance.

Hi,
I think that you have to run the rmiregistry in the
same directory path of your CalcImpl_StubNo, if you do that, your registry will never be able to supply the stub classes to client code - go read this
