The equivalent of MIDP's game api for standard platform ?

Hello,

I haven’t found the same library for a standard platform, and not for a mobile platform (as the MIDP’s game API). Maybe I haven’t made enough researches ?
I’d like to find a simple way to develop a Java 2D game, and think that there are some libraries to simplify the developer’s life.
That’s why I need help to know what I have to use ? Can someone gives me hints about some libraries ?

Thanks for your help

As I already posted in this post http://www.java-gaming.org/forums/index.php?topic=16300.0 -
the only engine I know of is - PSTROS - see :
