Socket will not send or receive the message (sending to 127.0.0.1)

Question

I don't know if it's my client or my server that's going wrong. I'll put the code here...can any one please tell me what I'm doing wrong? =(
CLIENT
public class ClientSession {
    private ChatWindow parentWindow;
    private BufferedReader in;
    private PrintWriter out;
    public ClientSession(ChatWindow parentWindow, String ip, int port) {
        this.parentWindow = parentWindow;
        try {
            Socket client = new Socket(ip, port);
            parentWindow.say("Connection succesfully established", true);
            System.out.println("Now connected to " + ip + ":" + Integer.toString(port));
            out = new PrintWriter(client.getOutputStream());
            in = new BufferedReader(new InputStreamReader(client.getInputStream()));
        catch(Exception e) {
            System.out.println("Error while connecting: " + e.getMessage());
            parentWindow.say("Failed to connect. Type /connect to retry.", true);
    public void sendMessage(String message) {
        System.out.println("Sending message: " + message);
        out.println(message);         
    }SERVER
public class Server implements Runnable {
    private int port;
    private HashMap<String, ChatWindow> chatWindowList;
    private String name;
    public Server(int port, HashMap<String, ChatWindow> chatWindowList) {
        this.port = port;
        this.chatWindowList = chatWindowList;
        this.name = "";
    public void run() {
        try {
            ServerSocket server = new ServerSocket(port);
            while(true) {
                Socket connection = server.accept();
                String ip = connection.getInetAddress().getHostAddress();
                ChatWindow chatWindow;
                if(chatWindowList.get(ip) == null) {
                    chatWindow = new ChatWindow(ip, port);
                    chatWindowList.put(ip, chatWindow);
                    chatWindow.connect();
                else {
                    chatWindow = chatWindowList.get(ip);
                    chatWindow.activate();
                    chatWindow.connect();
                ServerSession serverSession = new ServerSession(connection, chatWindow, name);
                Thread t = new Thread(serverSession);
                t.start();
        catch(Exception e) {
            System.out.println("Error at the server: " + e.getMessage() + e.toString());
    public void setName(String name) {
        this.name = name;
}SERVERSESSION
public class ServerSession implements Runnable{
    private String name;
    private ChatWindow chatWindow;
    private PrintWriter out;
    private BufferedReader in;
    public ServerSession(Socket connection, ChatWindow chatWindow, String name) {
        this.chatWindow = chatWindow;
        this.name = name;
        if(this.name.equals("") || this.name.equals("Please set name")) this.name = "No name set";
        try {
            out = new PrintWriter(connection.getOutputStream());
            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        catch(Exception e) {
            System.out.println("Error while writing to client:" + e.getMessage());
    public void run() {
        System.out.println("Session with Client accepted");
        loopTextAcceptance();
    public void setName(String name) {
        this.name = name;
    private void loopTextAcceptance() {
        try {
            chatWindow.say("reading...", true);
            while(true) {
                chatWindow.say("...", true);
                System.out.println("reading");
                String line = in.readLine();
                System.out.println("line read");
                chatWindow.say(line, false);
        catch(Exception e) {
            System.out.println("Error while recieving message: " + e.getMessage());
}thanks for reading!

Answer 1

the new code resulted from removing the ChatWindow stuff and any other places the errors can't be, is this better?
Server
public class ServerSession implements Runnable{
    private PrintWriter out;
    private BufferedReader in;
    public ServerSession(Socket connection) {
        try {
            out = new PrintWriter(connection.getOutputStream());
            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        catch(Exception e) {
            System.out.println("Error while writing to client:" + e.getMessage());
    public void run() {
        System.out.println("Session with Client accepted");
        loopTextAcceptance();
    private void loopTextAcceptance() {
        try {
            chatWindow.say("reading...", true);
            while(true) {
                chatWindow.say("...", true);
                System.out.println("reading");
                String line = in.readLine();
                System.out.println("line read: " + line);
        catch(Exception e) {
            System.out.println("Error while recieving message: " + e.getMessage());
}Client
public class ClientSession {
    private ChatWindow parentWindow;
    private BufferedReader in;
    private PrintWriter out;
    public ClientSession(String ip, int port) {
        try {
            Socket client = new Socket(ip, port);
            System.out.println("Now connected to " + ip + ":" + Integer.toString(port));
            out = new PrintWriter(client.getOutputStream());
            in = new BufferedReader(new InputStreamReader(client.getInputStream()));
        catch(Exception e) {
            System.out.println("Error while connecting: " + e.getMessage());
    public void sendMessage(String message) {
        System.out.println("Sending message: " + message);
        out.println(message);
        System.out.println("message sent");
    }output:
opening connection: 127.0.0.1 <- Client opening session, starting new ClientSession thread (not in code)
Now connected to 127.0.0.1:3300 <- ClienSession thread connected
Session with Client accepted <- Server accepting request from client (not in code)
reading <- ServerSession in the while(true) loop
Sending message: qdsf <- using the SendMessage function
message sent <- same function
<- nothing is said by the server =( d*mn you server!! read it!!! xD
