Subject: Security control through ClassLoader

Hi,

We have a signed Java applet that provides platform extensibility
through Rhino.  We need very strict control over what our users can do
in scripts because scripts are shared and executed between multiple
users (e.g. we need to restrict access to java.io).

I've looked into SecurityController but this doesn't seem to be quite
what I'm looking for.  I am currently using
Context.setApplicationClassLoader() to control how classes are loaded
for scripts.  This allows me to define a list of classes/packages that
we want to provide to script authors, but I'm unsure of whether or not
this is the best way to implement this and the documentation for this
method is a bit sparse.

If anyone has a better suggestion for controlling access to Java
packages I would very much appreciate your input.

Thank you,

Dale Beermann
