Native rendering on AWT Canvas

Hi,
I am using the AWT native interface for native rendering in a
Java window as described in:
http://java.sun.com/j2se/1.3/docs/guide/awt/AWT_Native_Interface.html
I would like to choose a graphics configuration for the Canvas,
which supports double buffering.
Right now I choose the graphics configuration with the following
piece of code:
GRAPH_CONF = 0;
GraphicsEnvironment genv =
GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = genv.getDefaultScreenDevice();
GraphicsConfiguration[] gc = gd.getConfigurations();


Canvas gl_canvas = new Canvas( gc[GRAPH_CONF] );
It seems that no matter which entry in the gc array I choose
there is no support for double buffering. It is the same on
all the Windows PC's I have testet this on.
I would like to know if there is a way to force the Canvas to
support double buffering.
Any comments are very welcome.
Kind regards
Soren Therkildsen
