Technique Needed To Create Such Java2D Look n Feel

I saw the following nice looking tool tips, created using JavaScript JQuery Toolkit.

I was planning to implement a similar look in my Java standalone application.

I was wondering what is the techniques needed to create such effect?

The things come out from my head are :

Transparency - java.awt.AlphaComposite
Gradient Background - java.awt.GradientPaint
Background Shadow - ???
White Line Around The Black Box - LineBorder ?

What is the keyword I shall look for, for the technology marked with ???

Thanks.
