Java games rock!

« Posted 2003-03-03 05:50:12 »

Hi,  8)All,
We wish to use Java 3D to do a robotics simulation project. In fact, we wish to use Java3D VRML loader and we have downloaded an example called "BVview" from Sun's website.
However, it cannot go through although we have copy vrml97.jar in the same position with j3dcore.jar.
It shows the error " in thread 'main' java.lang.NoClassDefFoundError: com/sun/j3d/loaders/vrml97/VrmlLoader"
I wonder is this the path problem?
But it seems our other Java 3D programs work fine except VRML loader problem.
Can someone give some suggestions?

Thank you so much!

Where did you get that VRML loader? The only loaders that ship with Java3D seem to be an OBJ loader and a Lightwave loader.

The file loader page at says that the loader in the Xj3D toolkit (available at ) is a rewritten and expanded version of Sun's VRML 97 loader, so you might want to download that toolkit. It seems to have problems with textures on objects in files generated by Maya though.

Its probably because you have installed a JRE (auto done by your browser) and a JDK on your machine. Java3D installs itself in both. You are probably not using the java.exe from where your vrml97.jar is located.

And read my replies in this thread about the vrml97 loader:;action=display;num=1046399441
