Java 3d Auto-Mapping Model Solution

Hey everyone, one of the many programs I've been working on lately is a skin stealer program, however it has a bit of a twist. Not only does it search and download skins, it is going to be able to show you a live model of the skin, walking or standing still, and will have a swanky interface, designed by my wonderful* sister, Horn. However, I'm getting hung up on the 3D modeling part, I have experience in blender, and that part wouldn't be too hard, but does anyone know a Java library, or some methods as to how I could put in a 3D model that automatically has the skin's .png texture mapped to it? Thanks for your help in advance, and please keep in mind that, while I do have 2 or 3 years of Java experience, I might be a little nooby in some unexplored areas, such as implementing 3D libraries.
