Java sending and receiving file (byte[]) over sockets

referring to the above question i just wanted to ask how can i put this code in loop for recieving multiple images from client side ???? I have tried but it doesnot stop at (count = is.read(bytes)) > 0 once it has read first time. Pleas help

I am not actually sure that I understand your question exactly, but I will try to help. So you want to have connection client/server for infinite amount of time? So try making both the server client and the client itself as threads and then put the tread in a loop. Try this sample.

connection = new Socket("IP",PORT);
        input = new DataInputStream(connection.getInputStream());
        output = new DataOutputStream(connection.getOutputStream());
        new Thread(new Runnable() {

        public void run(){
            while(true){
            try
            {
                System.out.println(">>" + input.readUTF());
            }
            catch(Exception e){
                try
                {
                    input.close();
                    output.close();
                    connection.close();
                }
                catch(Exception e2)
                {}
             }
            }
        }
        }).start(); 

        Scanner scan = new Scanner(System.in);

        while(true)
        {
            String data = scan.nextLine();
            output.writeUTF(data);
        }

This is the code for the client. You must also have ClienT Service thread that accepts all the data and sends back info! Hope I was helpful, because I am not really sure I understood the question correctly. Good Luck!
