				  e504. Defining and Exporting a Portable Remote Object
				
				1. Define the remote interface. 
				
				    import java.rmi.*;
				    
				    public interface RObject extends Remote {
				        void aMethod() throws RemoteException;
				    }
				
				2. Define the portable 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.
				
				    
				Using RMI over IIOP
				    > rmic -iiop RObjectImpl
				    
				    Using RMI over JRMP
				    > rmic RObjectImpl
				
				
				5. Create an instance of the remote object and bind it to a name service.
				
				    import javax.naming.*;
				    import java.rmi.RemoteException;
				    
				    
				    // JRMP: name = "rmi://localhost/RObjectServer";
				    // IIOP: name = "iiop://localhost/RObjectServer";
				    try {
				        RObject robj = new RObjectImpl();
				        new InitialContext().bind(name, robj);
				    } catch (NamingException e) {
				    } catch (RemoteException e) {
				    }
