You need not install Java3d if you are not planning on using GR domain.
If you plan on recompiling the GR domain, then install the Java 3D SDK
and runtime. If you plan on only running the GR domain demos, then
installing only the Java 3D runtime should be sufficient.
We have verified the demos with the
java3d-1_5_1-windows-i586.exe
installer.

If you are running Ptolemy II under Web Start, see Installing Java 3D for use with Web Start
If, when you run the GR domain demos, you get a message
about d3d8.dll
missing, then you probably need to install
DirectX.
DirectX can be downloaded from

in your JDK directory, for example
file:///C|/j2sdk1.4.2_04/demo/java3d/index.html
and run the HelloUniverse demo

java.lang.NoClassDefFoundError: javax/media/j3d/SceneGraphObjectThen be sure that the Java 3D jar files (j3daudio.jar, j3dcore.jar, j3dutils.jar,vecmath.jar) are located in the lib/ext directory for the plugin.
c:/Program Files/javasoft/JRE
and in theory the Java 3D installation should place the jar files, but
you may need to copy them by hand.
cp c:/j2sdk1.4.2_04/jre/lib/ext/* c:/Program\ Files/Java/j2re1.4.2_04/lib/extYou may also need to copy
J3D.dll
cp c:/j2sdk1.4.2_04/jre/bin/J3D.dll c:/Program\ Files/Java/j2re1.4.2_04/bin
