A Thread manages a connection from the outside--help me to finish it

Question

**RUN THIS CODE AND HELP ME--- THANKS A LOT**
EchoClient is thread which manage a connection from the outside.
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Random;
public class EchoClient extends Thread {
     private ServerSocket listenSocket = null;
     private Socket manageSocket = null;
     private int[] port = new int[9999];
     private BufferedReader in;
     private PrintWriter out;
     private int line;
     private int count;
     // No needed to mention
            //private ClientNode[] clientArray = new ClientNode[9999];
     private ManageClient[] manageClient;
     private final int CONNECTED = 1;
     private final int CONNECTING = 11;
     private final int DISCONECTED = 2;
     public void run() {
          try {
               manageClient = new ManageClient[9999];
               listenSocket = new ServerSocket(903);
               manageSocket = listenSocket.accept();
               while (true) {
                    in = new BufferedReader(new InputStreamReader(manageSocket
                              .getInputStream()));
                    out = new PrintWriter(manageSocket.getOutputStream());
                    line = in.read();
     // if Client send a variable(CONNECTING)
            // Server will send to Client a variable(CONNECTED) and port
            //to open a ChatFrame with that port
                    if (line == CONNECTING) {
                         System.out.print("have recieved");
          out.print(CONNECTED);
                     //randomize a port to send to client
          port[count] = (int) Math.ceil(Math.random() * 9999)
                    //creat a manageClient(Thread) to manage a seperate
                   // connection with a seperate Client
                         manageClient[count] = new ManageClient(port[count]);
                         manageClient[count].start();
                         out.print(port[count]);
                         count++;
          } catch (Exception e) {
               e.printStackTrace();
     public static void main(String[] args) {
          EchoClient e = new EchoClient();
          e.start();
}And a Login Frame which will send to server a varialble (CONNECTING) which requires to connect and keep waiting for a variable to Open a ChatFrame with a new port

}and this is ManageClient Thread...
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
public class ManageClient extends Thread {
     private ServerSocket ssClient;
     private Socket sClient;
     private int port;
     public ManageClient(int port) {
          this.port = port;
     public int getPort() {
          return port;
     public void run() {
          try {
               ssClient = new ServerSocket(getPort());
               sClient = ssClient.accept();
               while (true) {
                    BufferedReader in = new BufferedReader(new InputStreamReader(
                              sClient.getInputStream()));
                    PrintWriter out = new PrintWriter(sClient.getOutputStream());
                    String s = in.readLine();
                    if (s != null)
                         out.print("have recieved");
          } catch (Exception e) {
               e.printStackTrace();
}my problem...
At firts EchoClient will run.. and then Login but when I click to the Login button it has just only did before int line = in.readLine();(*** postion ***)
I don't know why it doesn't continue. It stops here and the login button is still visible(cause code has not finish)..
That's my problem...
