I found an interesting example of code for a b spline written in java script.
I would like to have the portion of it that computes the spline in JAVA ( I am working in NetBeans).
I don't need the user interface part, I only need the part that computes a point on a spline.
The web site is here.

It is a small set of code, but I don't understand javascript well enough to do it.
I was able to convert about 80% of it but not the whole thing.
