Do you guys have any example code about NURBS?

[flyingsword945]

Do you guys have any example code about NURBS implemented with JOGL? (the best: like the typical example code surface.c implemented with C and openGL)
I have to translate a OpenGL program written in C to Java. Firstly , I tried JGL, It's easy to use for it has one-to-one mapping of OpenGL but  It seemed to have some bugs in NURBS curve, so I switch to JOGL.
For time limited, Can anyone offer  me related example code?Thanks a million!
