XML Socket Server, Works but only after everyone disconnects!?

[craze3]

I have programmed an XML Socket Server to communicate with Flash.
It doesn't print out the messages it has received from the flash until the server has been shut down. Any ideas?

The part with the problem:

 
            //Create streams
            BufferedReader data_in = new BufferedReader(
                    new InputStreamReader(incoming.getInputStream()));
            PrintWriter data_out = new PrintWriter(incoming.getOutputStream());
            
            //Print sample welcome message
            data_out.println("<MESSAGE USER='John' TEXT='Hello, my name is John!' />" + EOF);
            data_out.flush();        
             
            boolean loopMAN = false;
            String line = null;
            while(null!=(line=data_in.readLine()))
            {
                //Print in server console
                System.out.println("Received message : " + line);
                //Write out to all clients connected
                data_out.write(line + EOF);
                data_out.flush();
            }
            
            //Close the server
            data_out.close();
            incoming.close();
            s.close();
            loopMAN = true;
            
            //Close the server if all clients disconnect
            if(loopMAN)
            {
                System.out.println("All clients disconnected!\nServer shut down.");
                System.exit(-1);
            }

The whole code:

            System.out.println("Server running! Now accepting connections...");
            Socket incoming = s.accept();
            incoming.setTcpNoDelay(true);

            }
            
            //Close the server
            data_out.close();
            incoming.close();
