I have made a Java Game Engine for awhile, and the status now is quite stable.
If anyone here want to make game with ease and supporting for OpenGL (both LWJGL and JOGL supported), could take a look at my game engine :
Golden T Game Engine (GTGE)
http://goldenstudios.or.id/products/GTGE/

Main features :
- support OpenGL as the render target, both LWJGL and JOGL supported!
- working flawlessly with Java 1.5
- default fps is changed to 100 fps
- enhanced sprite class
- more stable game loading
- changed how to load applet game
- fixed bugs in pixel perfect collision

Some demo game by GTGE that support OpenGL :

Game list :

Tell me what you think
I'm focusing on the ease of use, I'm designing the game engine as simple as possible.
I hope I got some review about this game engine in here. Thanks!

Your demo looks pretty neat. I was just wondering why the OpenGL performance is so bad. It runs dead slow and my CPU is pegged, but when I select Java2D it performs great.

Thanks.
Huh? The OpenGL mode is slower? Which one? JOGL or LWJGL?
JOGL has stability issue in ATI card, that is bugs on JOGL side, not my engine
The LWJGL should works great, no one ever have problem with it
Or perhaps your gfx card not support OpenGL.
Anyway which game that the OpenGL perform poor? RPG or Platformer?

"Which one? JOGL or LWJGL?" Both

It's probably my machine. I was trying it on a laptop. Then I tried it on my workstation with Linux and I could not get the OpenGL to work at all. Again, probably my graphics card.

Anyway the demo games are cool. They work fine for me in Java2D mode. How can I tell if my graphics card supports OpenGL?
 
I agree. Here's the link: http://aspose.com/file-tools
