Here is my server side code:
package server;
import java.io.*;
import java.net.*;
public class Serverside
{
public static void main (String [] args) throws Exception
{
System.out.println("The server is running.");
int clientnumber = 1;
ServerSocket server = new ServerSocket(9090);
try
{
while (true)
{
new cserver(server.accept(), clientnumber++).start();
}
}finally
{
server.close();
}
}
private static class cserver extends Thread
{
private Socket socket;
private int clientnumber;
public cserver(Socket socket, int clientnumber)
{
this.socket = socket;
this.clientnumber = clientnumber;
log("New connection with Client: " + clientnumber + " at " + socket);
}
private void log (String message)
{
System.out.println(message);
}
public void run()
{
try
{
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
//Message for Client
out.println("Hello, Client# " + clientnumber + ".");
out.println("Input Line\n");
while(true)
{ //System.out.println("Reading from Client\n");
String input = in.readLine();
// out.println(input);
if (input == null)
break;
out.println(input);
}
}catch (IOException e)
{
log("Error handling in client#" + clientnumber + ": " + e);
}finally
{
try
{
socket.close();
}catch (IOException e)
{
log("Could not close socket");
}
log("Connection with Client# " + clientnumber + " closed");
}
}
}
}
and here is my client side code:
package client;
import java.io.*;
import java.net.*;
public class clientside
{ public static void main (String [] args) throws IOException
{
Socket myclient = new Socket("localhost", 9090);
BufferedReader in =
new BufferedReader(new
InputStreamReader(myclient.getInputStream()));
PrintWriter out = new PrintWriter(myclient.getOutputStream(), true);
out.print("Hello server, end session\n");
for(int i=0;i<=2;i++)
{
String input = in.readLine();
System.out.println(input);
}
System.out.println("It is done");
myclient.close();
}
}
Now when I run the code, the client is able to receive the 2 lines from the server and print them but I am not able to send that one line from client to server and make it print. If anyone can help I would really appreciate it.
It is just a bug. When you change line 65 in Serverside.java to:
System.out.println(input);
and line 16 in clientside.java to:
out.println("Hello server, end session");
it works. So "System.out" instead of "out" in Serverside and "println" instead of "\\n" in client.
