3D Model tips in Java3D

Ok here is my situation. I have milkshape. I want to make 3D java applets using java3d(since that doesn’t requier any downloading. I need a way to load and display models in my game. I would like to have the ability to bable to easily to place my characters weapon in his hand with out having to do math(I am the worst at math) I know I need a loader, but hwat is involed in displaying the model? And getting all the rotations working(I have worked with 3d engines in c++, so java should be a breeze)

EDIT: Or is there a way to use a engine like JME in a applet with out library downloads?

Java3D is not part of J2SE.

It requires downloading. If you do it with JavaWebstart then you can automate the download, but it will still need to be downloaded by JavaWebstart the first time its used.
