Hi,
i was looking into the processing net library ( http://processing.org/reference/libraries/net/ )
and compiled the examples server and client

Server Code

1. import processing.net.*;
   Server myServer;
   int val = 0;
   
   void setup() {
     size(200, 200);
     // Starts a myServer on port 5204
     myServer = new Server(this, 5204);
   }
   
   void draw() {
     val = (val + 2)%255;
     background(val);
     myServer.write(val);
   }

and client code

1. import processing.net.*;
   Client myClient;
   int dataIn;
    
   void setup() {
     size(200, 200);
     // Connect to the local machine at port 5204.
     // This example will not run if you haven't
     // previously started a server on this port
     myClient = new Client(this, "172.18.104.27", 5204);
   }
    
   void draw() {
     if (myClient.available() > 0) {
       dataIn = myClient.read();
     }
     background(dataIn);
   }

when i run both the applications in the IDE it works fine but when i export the server app and run it nothing happens i.e. the client  is unable to see the data from he server

Thanks in advance
