import java.rmi.*;

public interface Hello extends Remote {

public String sayHello() throws RemoteException;

}

Hello.java(file1)

import java.rmi.*;

import java.rmi.server.*;


public class HelloImpl extends UnicastRemoteObject implements Hello
{

    public HelloImpl() throws RemoteException
    {
     super();
    }

    public String sayHello() throws RemoteException
    {

        return "Hello! Peter smith";

    }

}

HelloImpl.java(file2)

import java.rmi.*;

import java.rmi.server.*;

public class HelloServer {

    public static void main(String[] args)  {
        // TODO code application logic here

        try
        {

        System.setSecurityManager(new RMISecurityManager());

        Hello h=new HelloImpl();

        Naming.rebind("server", h);

        System.out.println("object is Registered");

        System.out.println("server is waiting for client reqest...");

        }catch(Exception e){System.out.println(e);}
    }

HelloServer.java(file3)

import java.rmi.*;

public class HelloClient {

 public static void main(String args[])
 {
 try{

  Hello h=(Hello)Naming.lookup("rmi://localhost/server");

  System.out.println("Client:Hello!");

  System.out.println("Server :"+h.sayHello());

    }catch(Exception e){System.out.println(e);}
 }
}

HelloClient.java

These are the four files(remote interface,remote interface implementation,client and server class) and ipaddress given for HelloClient is 192.168.0.52(given in my book) but i replaced with localhost in lookup method since iam running in stand alone application.Can any one help me run this program please!!!
