Hi
how add this socket client to strategy - Jforex platform?

import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class SocketClient {

        public static void main(String[] args) {
                try {
                        InetAddress host = InetAddress.getLocalHost();
                        Socket socket = new Socket(host.getHostName(), 7001);
                        ObjectOutputStream outputStream = new ObjectOutputStream(socket.getOutputStream());
                        outputStream.writeObject("SELL");
                        ObjectInputStream inputStream = new ObjectInputStream(socket.getInputStream());
                        String message = (String) inputStream.readObject();
                        System.out.println("Message: " + message);
                        inputStream.close();
                        outputStream.close();
                } catch (UnknownHostException e) {
                        e.printStackTrace();
                } catch (IOException e) {
                        e.printStackTrace();
                } catch (ClassNotFoundException e) {
                        e.printStackTrace();
                }
        }
}

Example please ...

Regards

and preferably this:

import java.io.*;
import java.net.*;
public class SocketClient {
   public static void main(String[] args) {
      BufferedReader in = new BufferedReader(new InputStreamReader(
         System.in));
      PrintStream out = System.out;      
      try {
         Socket c = new Socket("localhost",8888);
         printSocketInfo(c);
         BufferedWriter w = new BufferedWriter(new OutputStreamWriter(
            c.getOutputStream()));
         BufferedReader r = new BufferedReader(new InputStreamReader(
            c.getInputStream()));
         String m = null;
         while ((m=r.readLine())!= null) {
            out.println(m);
            m = in.readLine();
            w.write(m,0,m.length());
            w.newLine();
            w.flush();
         }
         w.close();
         r.close();
         c.close();
      } catch (IOException e) {
         System.err.println(e.toString());
      }
   }
   private static void printSocketInfo(Socket s) {
      System.out.println("Remote address = "
         +s.getInetAddress().toString());
      System.out.println("Remote port = "
         +s.getPort());
      System.out.println("Local socket address = "
         +s.getLocalSocketAddress().toString());
      System.out.println("Local address = "
         +s.getLocalAddress().toString());
      System.out.println("Local port = "
         +s.getLocalPort());
   }
}

thanks and bye

Hi,

Simple server multi connection:

import java.io.*;
import java.net.*;
public class ReverseEchoServer implements Runnable {
   private Socket con = null;
   public static void main(String[] args) {
      try {
         ServerSocket s = new ServerSocket(8888);
         printServerSocketInfo(s);
         while (true) {
            Socket c = s.accept();
            printSocketInfo(c);
            ReverseEchoServer v = new ReverseEchoServer(c);
            Thread t = new Thread(v);
            t.start();
         }
      } catch (IOException e) {
         System.err.println(e.toString());
      }
   }
   public ReverseEchoServer(Socket c){
      con = c;
   }
   public void run() { 
      try {
         BufferedWriter w = new BufferedWriter(new OutputStreamWriter(
            con.getOutputStream()));
         BufferedReader r = new BufferedReader(new InputStreamReader(
            con.getInputStream()));
         String m = "Welcome to Reverse Echo Server."+
            " Please type in some words.";
         w.write(m,0,m.length());
         w.newLine();
         w.flush();
         while ((m=r.readLine())!= null) {
            if (m.equals(".")) break;
            char[] a = m.toCharArray();
            int n = a.length;
            for (int i=0; i<n/2; i++) {
               char t = a[i];
               a[i] = a[n-1-i];
               a[n-i-1] = t;
            }
            w.write(a,0,n);
            w.newLine();
            w.flush();
         }
         w.close();
         r.close();
         con.close();
      } catch (IOException e) {
         System.err.println(e.toString());
      }
   }
   private static void printSocketInfo(Socket s) {
      System.out.println("Remote address = "
         +s.getInetAddress().toString());
      System.out.println("Remote port = "
         +s.getPort());
      System.out.println("Local socket address = "
         +s.getLocalSocketAddress().toString());
      System.out.println("Local address = "
         +s.getLocalAddress().toString());
      System.out.println("Local port = "
         +s.getLocalPort());
   }
   private static void printServerSocketInfo(ServerSocket s) {
      System.out.println("Server socker address = "
         +s.getInetAddress().toString());
      System.out.println("Server socker port = "
         +s.getLocalPort());
   } 
}

and link to page with cool examples
https://www.herongyang.com/JDK/Socket-Network-Communication.html
SSL socket

No way to guess at the answer...
Very wise people write these examples in Dukascopy wiki.
Like self and others make life difficult.
