Jess 7.0 also provides a way to create rules via XML (JessML) which, depending on your requirements, may be the easiest (and possibly the slowest) way to go.
See: jess.xml.JessSAXParser and: Jess70a4\examples\xml\sticks Jess70a4\examples\xml\mab I've not used this feature (yet) but I suspect it works as advertised.
