Have a look at Odonata -- they are attempting to have AWT working on 
SDL, which is what you want to do. I expect they have taken the approach 
which I outlined in the previous message. See 
http://adorphuye.com/gallery/Odonata/Odonata20040816 for a screenshot. 
If you can get the source to this, then it might be adaptable to
SDLJava. I think the project is also GPLed, so you can modify and 
redistribute the source if you want.

I'm just trying to find the Odonata CVS so I can check out the latest 
files (I'm interested in this myself), but it may not have anonymous 
access. There was also something about AWT / Swing being OpenGL 
accelerated in the latest version of Java, so perhaps that could also be 
used?

Chris
