Another question:
In trying to run my reconstructed version of Ralph Groves RIH, I get the
following error when I try to run it. since Ralph used Jess 4.0 I am
assuming that maybe the syntax he used has changed. If not maybe I have my
classes in the wrong place (not so likely as they are in same directory as
servlet).
Here is the error message:
*********************************
ReteControl: error in reset / run: Jess reported an error in routine new
while executing (new PARIHQueryPanel "Q: What type of legs does the
anim
al have?" 3 (create$ "no legs" "sna27.jpg" "(family snake)" "equal size"
"eqleg.
jpg" "(attr animal-has equal-size-legs)" "unequal size" "frg17.jpg" "(family
fro
g)") (fetch "ReteControl"))
while executing defrule MAIN::first-query.
Message: Class not found.
*********************************
The rule is written:
(defrule first-query
(initial-fact)
=>
(new PARIHQueryPanel "Q: What type of legs does the animal have?" 3
(create$
"no legs" "sna27.jpg" "(family snake)"
"equal size" "eqleg.jpg" "(attr animal-has equal-size-legs)"
"unequal size" "frg17.jpg" "(family frog)"
)
(fetch "ReteControl")
)
)
Any ideas ???
