java - Using client-server to move object on screen -


so i'm trying use client-server keylistener. when messages "#left" or "#right" sent server, should update graphical object , shift left calling map.repaint() method. instead, shifts object once , no further responses happen. posted below code. can offer solution?

// server

@override     protected void handlemessagefromclient(object msg, connectiontoclient client) {         // todo auto-generated method stub         if(msg instanceof string)         {             string message = msg.tostring();              if(message.equals("#connect"))             {                 string error = "already connected";                 matcher match = null;                 (int = 0; < matches.size(); i++)                 {                     if(matches.get(i).contains(client))                     {                         match = matches.get(i);
