   I'm not quite so certain as you that you can just call defineClass.
However, I suggest you ask the Rhino folks, you have reached the end of
my understanding of the issue.  The Rhino API requires that we supply
a classloader that implements one of their interfaces - so we need
a custom class loader which is forbidden in an Applet.

   If you discover that it is possible to compile scripts in an
applet please let us know what is involved.
