Hi!
I'm searching for the Java 3D News and Info, I just found that site:
https://java3d.java.net/
But I found too the JogAmp's Java 3D implementation (version 1.6.0 which works over JOGL 2), a continuation about that great API, you can find more in that links:
http://jogamp.org/wiki/index.php/Java3D_Overview
http://jogamp.org/wiki/index.php/Downloading_and_installing_Java3D
http://jogamp.org/wiki/index.php/Java3D_Tutorial
http://jogamp.org/wiki/index.php/Java3D_FAQ
They you'll can find all that you need to work with that.
I hope that info can help to people who is searching about it.
