matrix palette and vertex blend extensions

I wanted to use both the above extensions to do skeletal animation and I think I figured most of it looking at the ext documents from openGL. However, the code example at the bottom of the matrix palette document says to call:
glEnable(VERTEX_UNIT_ARB);
in order to enable the vertex units that will get read when transforming the vertices.
However I could find no jogl defined constant that matched up with VERTEX_UNIT
_ARB, even though the other constants for matrix palette are there.

Does this mean that I can’t use matrix palette’s or do I not need GL_VERTEX_UNIT__ARB to achieve skeletal animations?

The example is wrong. There is no GL_VERTEX_UNIT_(n)_ARB enumerated constant in the OpenGL header files. I have never used these extensions so I can’t recommend how to fix the code. However nowadays the way you should do this is with a vertex shader, not by using these obsolete extensions.

Thanks, I was unaware that these extensions were considered obsolete.
