Hello Experts,

I come up with another question! below is a part of my code. the idea is to get result from specific server and write back to Client but it doesn't close after sending .
pls have alook loop in line 30

====code ====

  public void run() {
 
    while (true) {
      try {
        Socket s = theServer.accept();        
        System.out.println("Client request is accepted!!!");                      
        PrintWriter out = new PrintWriter(s.getOutputStream(), true);              
        BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()), 1024 );  
       
        while (true) {          
              
              try{        
                      upServer = new Socket("192.168.0.5",4444);
                    outS = new PrintWriter(upServer.getOutputStream(),true);
                    inS  = new BufferedReader(new InputStreamReader(upServer.getInputStream()),1024);
                      
                    if(upServer.isConnected()) {                              
                           outS.println(iCmd);
                           outS.flush();                           
                     }
                     
                     String n = in.readLine();          
                      if (n == null) break;    
                      System.out.println("Client said: " + n );  
                                                      
                      outS.println(n);
                      outS.flush();
                      
                      System.out.println(n + " were sent to upper server");  
                      
                      while ( (result_out = inS.readLine()) != null ) {      
                                                         
                            System.out.println(result_out);
                            out.println(result_out);                                                                 
                        /// if (result_out.indexOf("Total") != -1) break;   =====>>> it work if i search for specifix Values and break up!
                  }
                  out.flush();
               }
               catch (IOException ex) {
                        System.err.println(ex);    
               }
               finally{
                  outS.close();
                  inS.close();
            }      
        } // end while        
       
        out.close();
        in.close();
       
      } // end try
      catch (IOException ex) {
            System.err.println(ex);
      }
    }  
  }
