Hi to all, i got the above title issue if anyone can help, i ll be in debt.
I 've got Processing 1.5.1 and windows 7.

Details:

1) I downloaded the UDP Library from http://ubaa.net/shared/processing/udp/
2) I put the extracted udp folder in the folder of mydocuments->processing->libraries as i have done for other libraries and work well.
3) I 've checked the name of the folder is the same with the .jar , in other words, "udp".

Then i am trying to run a script and the following message is the problem:

NoSuchMethodError: you may be using a library that's incompatible with this version of processing.

Exception in thread "Animation Thread" java.lang.NoSuchMethodError: processing.core.PApplet.registerMethod(Ljava/lang/String;Ljava/lang/Object;)V

Any help?
The test i ve been trying to run is here: http://arduino.cc/en/Tutorial/UDPSendReceiveString

Hi to all, i am new to this forum and the whole thing with processing.
I have a specific question to ask:

How can i connect my arduino with ethernet shield, getting temperature values from a sensor so they can be seen to a processing script?
In Arduino script, one gets the value, connects from the ethernet shield to a server and does what one likes.

In my case i want Arduino to just run the script of reading an analog input value from the sensor.
Is it possible?

I have made the serial connection work and read the values alright through the usb, but with ethernet shield? How can i get the value that arduino reads WITHOUT USB/Serial connection?

ps. i am using WAMP server etc, Windows 7

ps2. the code i want on arduino can be that simple and i just want temp to be available for use on a processing script without usb connection, only ethernet:

1. int inPin = 2;
2. float temp;
3. void setup()  { 
4. Serial.begin(9600);
5. }
6.      
7. void loop() {
8.   temp = ( analogRead(0) * 500.00) / 1024.00;
9.   Serial.println(temp);
10.   delay(1000);
11. }
