The X3D-Edit 3.2 Authoring Tool for Extensible 3D (X3D) Graphics supports the creation, checking, display and publication of X3D scenes. It is written in open-source Java and XML using the Netbeans 6.7 platform, making it suitable both as a standalone application and as a plugin module for the Netbeans integrated development environment (IDE).
X3D-Edit features include direct editing of X3D scenes using the XML (.x3d) encoding, embedded visualization of scenes using the Xj3D viewer, XML validation using X3D DTD grammars, X3D Schema grammars and X3D Schematron rules, drag-and-drop palette for X3D nodes, popup panels for node editing, and extensive help resources. Further features include ClassicVRML and X3D compressed binary encoding support, encryption and digital-signature authentication using XML Security standards, and additional X3D scene authoring support.

I had java version "1.7.0_67". There were some runtime errors, but the editor seemed to work more or less.
OK if you install Java 8:
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer
Tested with Ubuntu 10.04 LTS (the Lucid Lynx) on 16:22, 1 September 2010 (CEST).

(won't work)
Below is a summary from https://savage.nps.edu/X3D-Edit/
Name: X3D-Edit Update Center URL: http://www.movesinstitute.org/X3D-Edit/netbeans_modules/updates.xml
Won't work since plugins require by the X3D-Edit should be newer. Not possible to upgrade (we already did before)
Using the generic NetBeans IDE 6.9.1
Prior step:
Netbeans installation:
chmod a+x netbeans-6.9.1-ml-javase-linux.sh sudo ./netbeans-6.9.1-ml-javase-linux.sh
X3DD-Edit installation:
Name: X3D-Edit Update Center URL: http://www.movesinstitute.org/X3D-Edit/netbeans_modules/updates.xml
Result of this operation should look like this:

Done.
Prerequisite:
Java version: 1.6.0_21 64-bit (warning !)
This seems to a known issue, but is not documented in the overview page.
Tip: Consult the log files (e.g. c:\Users\YOU\AppData\Roaming\.x3deditor32\dev\var\log): In the log file, you can see it whining like Can't load IA 32-bit .dll on a AMD 64-bit...
Easy ways out (alternatives):
Java version 1.6.0_21 32-bit
Note: Oracle also distributes combined Java/Netbeans packs, but I prefer installing both separately
