OK, two things. First, to get a reference to the actual Fact object
that matches any pattern in any rule, you simply bind that pattern to
a variable in the rule left-hand-side using the "<-" operator:
(defrule foo-res
?foo <- (foo (name ?x))
=>
;; the variable ?foo is the matching jess.Fact object
...
But second, as you say this is a shadow fact and you want to "call a
method on it" I think what you mean is that you want to call a method
on the object that's being shadowed. There's a reference to that
object in the OBJECT slot of the shadow fact, so instead what you
actually want to do is
(defrule foo-res
(foo (name ?x) (OBJECT ?foo))
=>
;; the variable ?foo is the JavaBean and you can call "assign"
