(Yes I love double post in multiple threads to draw attention, just incase future people don't know where to look in a forum.)

Heres the link to BlueJ IDE, we use it at university to learn java.
http://www.bluej.org/

I was trying to get it to work with Processing, with limited success. I started by going to BlueJ > Preferences > Libraries - and added the Processing core.jar.




And I managed to get the Eclipse example working:

Code:

import processing.core.*; 
  
public class HelloP5 extends PApplet{ 
  
 public void setup(){ 
  size(200, 200); 
  stroke(155,0,0); 
 } 
  
 public void draw(){ 
  line(mouseX,mouseY,width/2,height/2); 
 } 
 
} 

It compiled, and I ran the applet from BlueJ - it doesn't work in the applet viewer, but does work if you run it in a web browser.

However, I cannot get the applet to compile if the color variable is used. I get the error "cannot resolve symbol - class color not found". This pretty much puts a dent in any normal processing work that I had planned involving color's.

Any suggestions welcome, I'm a bit stuck at the moment.
