Java MultiClient Server and Client Sending Issues

So I don't understand whats wrong. I'm trying to get a server that can send data to multiple clients. Data would be WhoSend+Data.

Server:

Code:

---

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.ServerSocket;
import java.net.Socket;


public class Server {

        /**
        * @param args
        * @throws IOException
        */

        static Socket incomingConnection=null;
        static ServerSocket ss;
        static int port = 25000;
        static int numberOFClients=0;

        static BufferedReader br;       
        static BufferedWriter bw;
        static String msg;

        public static void main(String[] args) throws IOException {               
                ss = new ServerSocket(port);
                System.out.println("Server Started and listening to the port "+port);       
               
                while(true){
                        incomingConnection = ss.accept();
                        Thread clientThread = new Thread(new ConnectionHandler(incomingConnection));
                        clientThread.start();
                        System.out.println(incomingConnection.getInetAddress()+" just connected.");
                }
        }
}

---

ConnectionHandler:

Code:

---

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.util.Scanner;


public class ConnectionHandler implements Runnable {

        Socket connectiontoClient;
        BufferedReader br;
        BufferedWriter bw;

        public ConnectionHandler(Socket incomingConnection) throws IOException {
                this.connectiontoClient = incomingConnection;
                br = new BufferedReader(new InputStreamReader(connectiontoClient.getInputStream()));
                bw = new BufferedWriter(new OutputStreamWriter(connectiontoClient.getOutputStream()));
        }

        public void run(){               
                try {
                        //Thread writeSocket = new Thread(new writeSocket(connectiontoClient));
                        Thread readSocket = new Thread(new readSocket(connectiontoClient));
                } catch (IOException e) {
                        e.printStackTrace();
                }
        }
}

---

readSocket:

Code:

---

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;


public class readSocket implements Runnable {
        Socket connectiontoClient;
        BufferedReader br;
        String incomingMsg;
        public readSocket(Socket connectiontoClient) throws IOException {
                this.connectiontoClient = connectiontoClient;
                br = new BufferedReader(new InputStreamReader(connectiontoClient.getInputStream()));       
        }

        public void run() {
               
                try {
                        while((incomingMsg=br.readLine())!=null){
                                System.out.println(incomingMsg);                               
                        }
                } catch (IOException e) {
                        e.printStackTrace();
                }
        }
}

Client:

Code:

---

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.util.Scanner;

import javax.swing.JOptionPane;


public class Client {
        static String host;
        static int port;
        static InetAddress address;
        static Socket socket;
        static OutputStream os;
        static OutputStreamWriter osw;
        static BufferedWriter bw;
        static String sendMessage;
        static BufferedReader br;
        static String receivedMessage;
        static Scanner scan;

        public static void main(String[] args) throws IOException {
                host = "127.0.0.1";
                port = 25000;
                address = InetAddress.getByName(host);
                socket = new Socket(address, port);
                scan = new Scanner(System.in);
                bw = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));       
               
                scan = new Scanner(System.in);
                while(true){
                sendMessage = scan.nextLine();
 
                bw.flush();
                bw.write(sendMessage);
                bw.flush();
               
                }
        }

}
