Java APIs

hi
i have an application that should start an rmi registery and then put/get objects into it using JNDI.
When i'm running it i'm getting the following exception:]

import java.rmi.RemoteException;

public class TestClassik implements IServerRegistry {

	public int testFunction() throws RemoteException {
		// TODO Auto-generated method stub
		return 0;
	}

}

IServerRegistry

package org.ro2helpers.gateway;

import java.rmi.Remote;
import java.rmi.RemoteException;

public interface IServerRegistry extends Remote {
	public int testFunction() throws RemoteException;
}
