Hi Gary, You might want to look into Rhino, the Java implementation of the Mozilla JS engine <http://mozilla.org/rhino/>, or if you're keen, check out SpiderMonkey (the C implementation) <http://mozilla.org/js/spidermonkey/>.
I've used SpiderMonkey in an (ongoing) personal project, and it's rather easy to implement, I'd imagine Rhino would be the same. -- Lindsay Evans. Developer, Red Square Productions.
