I have a similar problem.
I wanted to run a Java3D applet that uses the VRML97 loader and my applet
also requires to do some file I/O to same the user's setting.
This is the error message that I get.
Exception loading file:= java.security.AccessControlException: access denied
(java.lang.RuntimePermission createClassLoader)
java.security.AccessControlException: access denied
(java.lang.RuntimePermission createClassLoader)
Anybody have experience using VRML97 loader?
