Always On Top

[JetBlack69]

I'm writting a java program that calls a linux program xvkbd. Once this program is called, I would like it always on top of my java windows. Is there any way I can program X windows or java or c++ to do this? This is running on gnome ( or mwm in the near future) on Linux 2.6 Fedora. I know I can right-click the title bar and select On Top, but is ther a way to do that programmatically?

Thanks.
