RMI + THREADS

Hello I need help..

I want to do this class:

public interface UserInterface extends Remote {
public void start() throws java.rmi.RemoteException;
public void run() throws java.rmi.RemoteException;
}
public class User extends UnicastRemoteObject implements
UserInterface, Runnable{
public void start() throws java.rmi.RemoteException{
...
}

public void run() throws java.rmi.RemoteException{
...
}
}
It doesn´t work because the method run() declared in class User cannot
override the method of the same signature declared in interface
java.lang.Runnable. That method doesn´t throws
java.rmi.RemoteException.

But the UserInteface extends remote and the methods must throw
java.rmi.RemoteException.
Someone knows what can I do ??
