{
public String appletMessage() throws RemoteException;
}
----------------------
implementation class:
import java.rmi.*;
import java.rmi.server.*;

public class AppletMessImp extends UnicastRemoteObject implements AppletMess
{
public AppletMessImp() throws RemoteException
{
super();
}

public String appletMessage() throws RemoteException
{
return "Hello, Object One Welcome's You";
}

}
----------------------------
Server :
import java.io.*;
import java.rmi.*;
import java.rmi.server.*;
public class AppletMessServer
{
public static void main(String args[])
{
//System.setSecurityManager(new RMISecurityManager());
try
{
AppletMess sobj= new AppletMessImp();
System.out.println("main");
Naming.bind("asit", sobj);
System.out.println("Remote Object bound in registry");
}
catch(Exception ee)
{
System.out.println("Implimentation error:"+ee.getMessage());
ee.printStackTrace();
}
}
}
------------------------
