Hi friend,

import java.io.*;
import java.rmi.*;
import java.rmi.registry.*;
import java.rmi.server.*;

public class EchoServer implements Echo {
public String echo(String value) {
return value;
}
public static void main(String[] args) {
try {

//create an object
EchoServer serv = new EchoServer();

//export the object
Echo remoteObj = (Echo) UnicastRemoteObject.exportObject(serv);

//make object findable
Registry regis = LocateRegistry.getRegistry("localhost",8080);
regis.rebind("ECHO", remoteObj);

BufferedReader rdr = new BufferedReader(new InputStreamReader(System.in));

//Serve clients
while (true) {
System.out.println("Type EXIT to shutdown the server.");
if ("EXIT".equals(rdr.readLine())) {
break;
}
}
//unregister object
regis.unbind("ECHO");

//unexport object
UnicastRemoteObject.unexportObject(serv, true);
}
catch (Exception e) {
e.printStackTrace();
}
}
}

-------------------------------
import java.rmi.*;

public class EchoClient {
public static void main(String [] args) {
try {
System.out.println("Connecting to echo server...");
Echo e = (Echo) Naming.lookup("ECHO");
String result = e.echo("Hello");
System.out.println("Echo returned " + result);
}
catch (Exception e) {
e.printStackTrace();
}
}
}
-------------------------------------
import java.rmi.*;
public interface Echo extends Remote {
public String echo(String value) throws
RemoteException;
}

You will need three console windows to start the RMI registry, run the RMI server, and run the RMI client. In all of these windows, make sure your class path is set to the directory where the various Echo classes live. Then, run the following three commands, one per window, in this order:

rmiregistry
java EchoServer
java EchoClient


---------------------------------------------------------


Thanks.
