Hi,

I'm trying to view 3d objects (which I have been able to do in the past), 
but now I'm receiving the following error.

sage: L = RootSystem(['A',3,1]).ambient_space()   
sage: W = L.weyl_group()
sage: L.plot(alcoves=[W.one()], reflection_hyperplanes=False, bounding_box=2
)
---------------------------------------------------------------------------

I'm currently running Sage 6.6rc0 and I have double checked that I have 
Java installed.  Any ideas for how to get Sage to recognize my Java? 
 Thanks in advance for the help!

Best,
Ben
