Lotus uses the Rhino package from Mozilla.

Rhino is an excellent package, it can even compile the Javascript to Java
byte codes on the fly.

I'm building a system that integrates XT and Rhino, but I'm doing it with a
non-standard mechanism to address my specific needs. To implement it right
the XT servlet clones an instance per thread and Rhino doesn't support
cloning so there is no real simple solution. There are ways around the need
for cloning Rhino but they are complicated.

Lotus XSL avoided this problem by always interpreting the Java Script.
Therefore there is no state for Rhino to hold and no need to clone. But this
solution is too slow for a production servlet.
