3D import statements?

Hello, I'm relatively new to java (i've had one high-school class) and I am trying to make a 3D map. I found a tutorial that seems to do what I want to do, but when I try to compile it there are tons of errors. I believe that the tutorial is somewhat old, so the import statements are outdated. I looked on the API, but I couldn't find any of the classes. Does anyone know what these are?

import javax.media.j3d.*;

import javax.vecmath.*;

import com.sun.j3d.utils.universe.*;

import com.sun.j3d.utils.behaviors.vp.*;

import com.sun.j3d.utils.applet.MainFrame;

import com.sun.j3d.loaders.Scene;

import com.glyphein.j3d.loaders.milkshape.*;

The tutorial is here: http://www.newview.co.uk/tutorials/java3d/

Thanks for any help!
