Java RMI ServerException - java.lang.ClassNotFoundException: org.prog.rmi.RmiServer_Stub

Question

I have inherited some Java RMI client/server code, and while it runs fine on one machine, I haven\'t been able to get it to run in my dev environment.

The problem is whe

Answer 1

You haven't regenerated the stub with rmic, or the Registry doesn't have access to it via its classpath.

Answer 2

After some further investigation and following RMI tutorials it appeared that there was a problem with the RMI registration server on port 1099.

When I stared the RMI registration server on another port (e.g. 2005) and changed these lines of code

LocateRegistry.createRegistry(2005);

and

Naming.rebind("//127.0.0.1:2055/RmiServer", obj);

This ran sucessfully without errors and my client was able to connect.

I hope this answer helps others with this error. Let me know if anyone needs any more detailed information.
