this isn't a source file, it's a Java
executable. Boot to LINUX and save this file to
ReflectanceLab.class. Run it with the following command:
java -classpath
/usr/share/java/j3dcore.jar:/usr/share/java/j3dutils.jar:/usr/share/java/vecmath.jar:.
ReflectanceLab
The classpath string should not have any spaces in it and there should
be colons between each directory path. Don't forget that last
colon and period.
