Hi,

I've modified the chatserver-example to write incoming data to a textfile but as easy as that sounds it doesn't really return anything. The weird thing is that the incoming messages are displayed in the draw-window as "text"-objects but i can't get the strings to print in either the outputfile or the console, it always seems to returns null. Any clue?

Thanks,
FRid

The client

1. import processing.net.*;
   
   Client c;
   String data;
   
   void setup() {
     size(200, 200);
     background(50);
     fill(200);
     c = new Client(this, "127.0.0.1", 8888); // Connect to server on port 80
     c.write("GET http://localhost:8888/foursquare?code=CODE/ HTTP/1.1\n"); // Use the HTTP "GET" command to ask for a Web page
     c.write("Hello, anybody"); // Be polite and say who we are
     c.write("out there?");
   }
   
   void draw() {
     if (c.available() > 0) { // If there's incoming data from the client...
       data = c.readString(); // ...then grab it and print it
       //println(data);
     }
   }
   
   

The server:

1. import processing.net.*;
   
   int port = 8888;
   boolean myServerRunning = true;
   int bgColor = 0;
   int direction = 1;
   int textLine = 60;
   
   Server myServer;
   ArrayList strings;
   PrintWriter output;
   
   void setup()
   {
     size(1000, 500);
     textFont(createFont("SanSerif", 16));
     strings = new ArrayList();
     myServer = new Server(this, port); // Starts a myServer on port 10002
     output = createWriter("output.txt");
     background(0);
   }
   
   void mousePressed()
   {
     // If the mouse clicked the myServer stops
     for (int i=0;i<strings.size();i++) {
       String s = (String) strings.get(i);
       output.println(s);   
     }
     output.flush(); // Writes the remaining data to the file
     output.close(); // Finishes the file
     myServer.stop();
     myServerRunning = false;
     exit(); // Stops the program
   }
   
   void draw()
   {
     if (myServerRunning == true)
     {
       text("server", 15, 45);
       Client thisClient = myServer.available();
       if (thisClient != null) {
         if (thisClient.available() > 0) {
           text("mesage from: " + thisClient.ip() + " : " + thisClient.readString(), 15, textLine);
           String temp = thisClient.readString();
           strings.add(temp);
           println(thisClient.readString());
           textLine = textLine + 35;
         }
       }
     }
     else
     {
       text("server", 15, 45);
       text("stopped", 15, 65);
     }
   }
