But you don't do well in adding CEP by pushing code on top of an unmodified Engine like Jess because Rete's natural "eagerness" to evaluate conditions and patterns must be reined in as soon as the "future" or anything depending on "now" must be considered. This doesn't mean that you can't solve CEP tasks with an engine like Jess as is, but it's rather inconvenient. their algorithm is more capable, when in fact its just open source > libraries and middle-ware wrapped around a Rete.
