I compiled PovRay on Solaris WITH OUT X support and I use Java
Runtime.getRuntime().exec() to invoke it with out any problems. My java code
also runs on Windows and has no problem except that you need to add the
/EXIT as one of the cmdline args (so it exits when it is done).

Process process = Runtime.getRuntime().exec(POVRAY + " " +
options.substring(4)); //remove the data keyword

I am writing (currently functional) a distributed renderer using  Java,
Povray and some C++ (to recombine the output) and I will be testing on some
Linux nodes (currently all the nodes are Sparc/Solaris) in the next 1-2
weeks. So I will let you know if my Java code holds up or fails.
