Yes, Tornadolabs J3dtree Scenegraph Tree Viewer works -----------------------------------------------------
I've used it and it's been documented in the Java3d archives.
Here's an image of it Running ( and documentation follows ):
http://www.frontiernet.net/~imaging/sc_vrml_picking_with_java3d.jpg | http://www.frontiernet.net/~imaging/games_with_java3d.html
It's one of many programs that uses Sun's VRML Loaders vrml97.jar files ( along with Nasa's Fastscript3d Web apps and Sun's Java3d Scenegraph Editor, see below for both ).
The j3dtree_jar.jar file contains several jar files, ".bat" and ".sh" files to run it on Windows and Linux, and a ".wrl" VRML file in the VRML directory, and the .java source files ( get vrml97.jar separately ).
"Documentation" -------------
1) Get the ".jar" files
2) type: jar -xvf j3dtree_jar.jar
3) type: ( on Windows ): run_j3dtree.bat
---- ( on Linux ): sh ./run_j3dtree.sh
4) click on the sphere, cylinder, or box
5) yell: " Wow, it works ! "http://home.rochester.rr.com/javajava/SourceCode/j3dtree_jar.jar
Run the batch or shell file and it opens to windows, one is the 3d scene of VRML objects that you can click on, and the other contains the Scenegraph tree which you can also click on to expand the nodes, clicking on the 3d objects causes the name of the "picked" object to be displayed in the console window.

j3dtree.jar & related files ( Selman's Scenegraph Viewer Demo ) ---------------------------
Java ARchive contains: Selman's j3dtree.jar, VrmPickingTest.java etc.
You must also obtain Sun's VRML Loaders: vrml97.jar
To extract the files type:
jar -xvf j3dtree_jar.jar
To run on Windows type: run_j3dtree.bat
To run on Linux type: sh run_j3dtree.sh

TornadoLabs is no more, the original content is gone, Selman moved on to BEA.com then ILOG.com, Selman is still doing Java but not Java3d.

Another VRML Scenegraph Viewer is Sun's Java3d Scenegraph Editor wich also uses Sun's VRML Loaders:

The Sun VRML Loaders can also animate Web3d.org's VRML based Human Avatars ( H-Anim ) in a browser.
