Processing 3.1.1 error with Arduino Leonardo

[Daniel Petre]

Hi, so uploaded the Arduino Leonardo code to my r3 Leo and when running Processing with your code it says "Could not run the sketch" and breaks at:

println(Serial.list()); // print a list of available serial ports

any ideas please?

You may need to select the right serial port.
Please send the entire error message that processing gives you

got a Uno, the Leonardo was kindof faulty.
