B i n d E x c e p t i o n :   A d d r e s s   i n   u s e.   The following is the code:   public class UsersServlet extends HttpServlet implements Runnable{     static int SERVLET_PORT=10000;     ServerSocket  serverSocket;     RandomAccessFile myfile;     Thread mythread=new Thread(this);     public void run(){     try{         serverSocket = new ServerSocket(SERVLET_PORT);                        while (true)                        handleClient(serverSocket.accept());           }catch(IOException e){}                   }     public void init(ServletConfig config) throws ServletException {         super.init(config);         mythread.start();           }     public void handleClient(Socket client){     new UserConnection(this, client).start();   Any suggetion is helpful to me.   Regards Huyong
