Shape window is not working in " Processing 2"

import java.awt.*;
import com.sun.awt.AWTUtilities;
import java.awt.GraphicsDevice.*; // PC only
import java.awt.Shape;
import java.awt.AWTException;
import java.awt.geom.*;
int d = 500;
void setup() {
size(d,d);
background(255);
Shape shape = null;
frame.removeNotify();
frame.setUndecorated(true);
shape = new Ellipse2D.Float(0,0,d,d);
AWTUtilities.setWindowShape(frame, shape);
}
void draw() {}

Error:

No library found for com.sun.awt

java.lang.NullPointerException

Since Oracle bought Sun, they eliminated the com.sun packages which were private (not open sourced) and undocumented.
I vaguely recall there is a replacement, I suggest to push further your search.
Mmm, yes, that's code from old experiments, the shaped windows became official in further versions of Java, using an official API. Java 7 removed these packages, still in Java 6, apparently. Are you using Processing with Java 7?

See

and
http://bazaar.launchpad.net/~philho/+junk/Processing/files/head:/_QuickExperiments/_Java/WindowTransparency/
for my own experimentations.

Yes I am using it with Java 7 update 21, 32 bit version on windows 7 system ..

PhiLho can you show me an example of circular shapeWindow .. very basic so that I can try some other complex shape. I have tried you code TranslucentShapedWindow.pde but couldn't understand how to control the shape of window .....

thanks

Have you looked at the article from Oracle? They show how Java 6 API maps to Java 7 one.
How are you using Java 7 with Processing on Windows? (just curious)

I've mentioned that I don't use the old bundled Java which comes w/ Processing a couple of times.
Here's a post where I even give some general instructions for it:
http://forum.processing.org/topic/how-do-i-point-processing-to-a-particular-java-instance

In the old Processing 1.5.1, removing /java subfolder was enough in Windows.
But now, Processing devs think that it's too "dangerous" or something for dummy programmers using Windows!
So, we have to cheat Processing v2+'s launcher to think it's using the Java from that subfolder
by using a junction for the real thing!

Linux doesn't have this problem. However, a warning message pops up instead of the opening screen.
And it says that it's not "fond" of this Java! And I dunno how to remove that!!!
