Richard, I think the general answer for Java 3D is no. I believe there are hacks using Polygon offsets and duplicating your geometry (one wireframe, one solid rendered) and rendering both (you move the wireframe version a little closer to the viewer), but this is unlikely to be suitable for all cases and work on all hardware.
I suggest you consult OpenGL documentation for more general discussions of this.

Does anyone know how I could get just the lines along the outermost outline of the entire polyhedron? For instance, consider a vertical cylinder. The approach described below would show the outline of the two circular faces, but there would be no vertical edges representing the body of the cylinder. I need a solution that shows the entire outline of the 3d shape, as well as (possibly) the face boundaries, but none of the interior edges.
