well .. you can try Graphics g = this.getGraphics() !
And awt-render _after_ swapping the buffer, 
if you use double-buffering.

This will not work in the current GL4Java up to 2.5.0-test2 
if an new native window is created (see the native debug out info's) !

In the upcoming 2.5.0-test3 this should work, if you use the new factory api,
because the java window itself will have all the capabilities needed 
while using the JDK 1.3 class GraphicsConfiguration internaly
(-> no more new native window will be created) !

well, this is true, e.g. for an overlayed textual info ..

may be you have to wait for the new version ...
