Java 3D in fullscreen. How?

Question

I need to display animated 3D images in fullscreen exclusive mode and I'm using active rendering as opposed to passive. How can I display parts of the virtual universe in fullscreen mode with active rendering? Many, many thanks to whoever can help me out with this.
