originally it is a BoundingSphere, but i need a BoundingBox that fits

That, unfortunately is a function of the way Java3D works. Even if you
provide a bound _box_ shape, when you query it back, you always get a
sphere.
Well, not always. If you would like to have a custom bounds, you should
call the method setBoundAutoCompute(false) BEFORE you set the bounds,
then it will return and use your custom bounds. If you do not do this
call, it will as Justin said always return and use a autogenerated Sphere.
But beware the node above will again return a autogenerated sphere even
though your node with the custom bounds is the only child. Also notice
that if you set setBoundAutoCompute(false) then getBounds will return
null, and this will make Java3D throw an exception like the one below,
and stop rendering, so always supply a bounds if auto is set to false:
java.lang.NullPointerException
