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:
Java 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:
Java 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:
Java 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:
Java 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();
		
		}
	}

}
