如何在JDK 1.6中使JFrame透明？

Question

In JDK 1.7 I use setUndecorated(true); and setBackground(new Color(0, 0, 0, 0)); to make my frame transparent.

This works perfectly but when I change the project to 1.6 this same code just makes the frame its original blue-ish color. I don't want to make my form Opacity lower as in alpha transparent. I want to have it more like a splash screen, where GD draws SOLID non opacity lines but the surrounding is completely click-through and transparent.

What is the code in 1.6 to do this?

I stumbled upon a neat little hack that instead of actually being transparent, it takes a screenshot and adds that little segment as the background.

maybe there is this issue As of the Java Platform, Standard Edition 6 (Java SE 6) Update 10 release, you can add translucent and shaped windows to your Swing applications.
