1. Define the remote interface. 
    import java.rmi.*;
    
    public interface RObject extends Remote {
        void aMethod() throws RemoteException;
    }

2. Define the remote object implementation. 
    import java.rmi.*;
    import java.rmi.server.UnicastRemoteObject;
    
    public class RObjectImpl extends UnicastRemoteObject implements RObject {
        public RObjectImpl() throws RemoteException {
            super();
        }
        // All remote methods must throw RemoteException
        public void aMethod() throws RemoteException {
        }
    }

3. Compile the remote object implementation. 
    > javac RObject.java RObjectImpl.java

4. Generate the skeletons and stubs. 
    > rmic RObjectImpl


5. Create an instance of the remote object and bind it to the RMI registry. 
    try {
        RObject robj = new RObjectImpl();
        Naming.rebind("//localhost/RObjectServer", robj);
    } catch (MalformedURLException e) {
    } catch (UnknownHostException e) {
    } catch (RemoteException e) {
    }
