I don't know if you can use them with swing, i think you can.. but swing is lightweight
and jogl heavyweight. That is a bit of a problem

I don't want to use jogl because my app is SWING client for bussines app.
Since jdk 1.5 java 2D can use OpenGL for rendering. I think that swing
components use java 2D api for painting so it could use opengl if it is
avaliable. But when I enable openGL in my app, I get scramled sreen, or
sometimes it freez.

The OpenGL layer is still a bit buggy. It's known to swap color-channels in
Volatile/BufferedImages. The more bug-reports to Sun, the better.

And don't forget to update drivers ofcourse.

I don't think Sun it too interested in OpenGL support. They want java3D to
catch on...which wouldn't necessarily be a bad thing if there was more
literature avilable about the API and a REAL scene-graph editor was
available.

I have to disagree strongly here. Sun more or less abandoned Java3D and made
it available to the community. They may want Java3D to catch on, but they
don't put much effort in it.
