using network libraries

ieee

hello, good morning to you..

i tried to use network libraries and i got an error called:
"the function active() does not exist."

bad !!

here's the simple code used :

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 + 1) % 255;
  background(val);
  if (myServer.active() == true) {
    myServer.write(val);
  } else {
    println("Server is not active."); 
  }
}

void mousePressed() {
  myServer.stop();
}

many thanks for your replies..

Method active() belongs to class Client instead: :-\"

but things strange , it is in the processing server master example that i find this example..i' m lost !!...look :

https://processing.org:8443/reference/libraries/net/Server_active_.html

things i want to do is to transmit data from my i2c raspberry to a client that is far away..and then process my signal... first, processing must works fine with a minimum i think...

i'm beguining in processing...have you a example of client-server applications that client receive what server send ( for example in ascii codes...why not ) or may be an url adresse that poeple makes tests about it....??

bets regards..

I don't have any such hardware. Sorry I can help you there. :(

Oh, indeed. Missed the active() reference for class Server too. =P~
But what I don't understand is why you've got: "the function active() does not exist."
Your example compiles normally for me in my Win7 laptop w/ 64-bit Processing v3.1.2. >-)

@ieee --

1. Did you install the Processing Network library using the Contributions Manager?
2. If so, which version of the library is it showing as installed?
3. Is the code posted above the exact code you are running in your sketch window? are there other errors, and do the errors identify line numbers?

If the library is installed then it looks like the method Server.active() should indeed exist -- as per the latest source code:

https://github.com/processing/processing/blob/master/java/libraries/net/src/processing/net/Server.java#L191

you where right Jeremy...i install the lastest version of processing and its works fine...good.. i used to test in the "2" version before on a 32bits system... many thanks to all of you..;)
