I'm new to rmi and i'm currently developing a network application (for my final year prooject).

The application comprises a server and client which are implemented using rmi. Both components (server-client) compile correctly and the server runs without a glitch until the client application tries to make a connection to the server.

When i run the client application a nested (ClassNotFound)error message is returned from the server. The offending class is the stub class for the server application.

Could someone please give me a few pointers on what i might be doing wrong, i thought it might be something to do with my classpath environment but i've tried altering it and the same error occurs.

=>the server class is called DataAccess
=>the client is EmployeeInterface

error connecting to server error unmarshalling return;
nested exception is:

java.lang.ClassNotFoundException: server.DataAccess_Stub

java.rmi.UnmarshalException: error unmarshalling return;
nested exception is:

java.lang.ClassNotFoundException: server.DataAccess_Stub
