Client doesn't get output when local address is replaced by server address

[Chandrahas Tore]

Client doesn't get output when local address is replaced by server address and client is run from other machine.

Below code works fine when Client and Server are running on same machine but when client runs from other machine with Server's IP address, Client doesn't get any output.

TestClient.java

import java.io.*;
import java.net.*;

public class TestClient{

        public void go(){
                try{
                        Socket s = new Socket("127.0.0.1",5791); // loopback address is then replaced by server ip address
                        BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
                        String str = br.readLine();
                        System.out.println(str);
                        br.close();
                }
                catch(IOException ex){
                        ex .printStackTrace();
                }
        }

        public static void main (String[] args){
                TestClient client = new TestClient();
                client.go();
        }
}

TestServer.java

    
import java.io.*;
import java.net.*;

public class TestServer{

        public void go(){
                try{
                        ServerSocket Serversock = new ServerSocket(5791);

                        while(true){
                                Socket sock = Serversock.accept();
                                PrintWriter writer = new PrintWriter(sock.getOutputStream());
                                writer.println("test");
                                writer.close();
                                System.out.println("test");
                        }
                }
                catch(IOException ex){
                        ex.printStackTrace();
                }
        }

        public static void main(String[] args){
                TestServer server = new TestServer();
                server.go();
        }
}

Can someone reply where it's going wrong?

Thanks in Advance

The code is fine.
The only problem is with IP : "127.0.0.1"
When you run it on the other machine you need to change it, means you have to give here the IP of server whom you are calling.
That's the only chance of error!!

One more error is possible is of port:
if your port is already in use.
So, better check if that port is free or not.

Let me know what error you are actually getting?
