Looks like you are trying to load a vrml1 file into a vrml2 parser.
Also, please note that the working-groups page is somewhat out of
date. I'll update it, but until then a more recent snapshot of the
binaries is available from http://www.web3d.org/TaskGroups/x3d/sun/cvs.html
Substitute x3d.jar for vrml97.jar where you see it in your
instructions.
Regards,
