This is sort of Java-like.

I've quite a bit of experience using JRules but I've recently chosen to
use JESS as it seems more natural and flexible in many ways. The big
difference for me is both a blessing and a curse. In JRules EVERYTHING is
a Java class so facts are typically modelled with embedded relationships.

Hi again,
I have the following problem with the combination of the logical CE and
backward chaining by using rules like:
(do-backward-chaining answer)
(defrule bwc-example
(logical (initial-fact) (foo (id ?id)))
=>
(assert (something))
Backward chaining occurs for the foo (shadow)fact

A quick google for "Jess planner" turns up evidence that it's been
done several times before: see
http://www.cs.umbc.edu/~mariedj/papers/icaps-ws03.pdf
and
http://www.cs.ucsb.edu/conferences/PUI
Does it make sense to implement a simple planner with Jess?
I'm thinking of a plan template as such:
(deftemplate plantemplate
(multislot preconditions)
(multislot postconditions))
But then how to generate the defrules automatically to match the
preconditions?
Thanks for any ideas,
