Just comparing your two lines
(defglobal ?*airTempFvar* = new FuzzyVariable "airTemperature" 0.0 100.0
"Deg C"))
and
(defglobal ?*fanSpeedFvar* = (new FuzzyVariable "fanSpeed" 0.0 1000.0
"RPM"))
It looks like you are missing a paren before "new" in the former.

Thanks alot Mr. Orchard for your time,
To run your example (in "How to use the Fuzzy Extensions with Jess") I
simply set the "Jess main class" under the "Jess Application" tab in Run
Configurations to nrc.fuzzy.jess.FuzzyMain, but didn't know what to do with
the "Arguments" tab so I left it blank and runned the example. Should we
set
the "Program arguments" or "VM arguments" under the arguments tab to
something??
Also, regarding the other example I found in FuzzyJessNRC-44882.pdf
(attached to this email), once I run it (from run configurations...), it
gives a whole lot of errors which some are following the example code here;
(import nrc.fuzzy.*)
;; Two globals to hold our FuzzyVariables for air temperature and fan speed
(defglobal ?*airTempFvar* = new FuzzyVariable "airTemperature" 0.0 100.0
"Deg C"))
(defglobal ?*fanSpeedFvar* = (new FuzzyVariable "fanSpeed" 0.0 1000.0
"RPM"))
(defrule init "An initialization rule that adds the terms to the
FuzzyVariables"
=>
;; the nrc FuzzyJess functions are loaded
(load-package nrc.fuzzy.jess.FuzzyFunctions)
(bind ?rlf (new RightLinearFunction)) (bind ?llf (new LeftLinearFunction))
;; terms for the air temperature Fuzzy Variable and fan speed Fuzzy
Variable
(?*airTempFvar* addTerm "cold" (new RFuzzySet 0.0 20.0 ?rlf))
(?*airTempFvar* addTerm "OK" (new TriangleFuzzySet 0.0 20.0 35.0))
(?*airTempFvar* addTerm "hot" (new LFuzzySet 20.0 35.0 ?llf))
(?*fanSpeedFvar* addTerm "low" (new RFuzzySet 0.0 500.0 ?rlf))
(?*fanSpeedFvar* addTerm "medium" (new TriangleFuzzySet 250.0 500.0 750.0))
(?*fanSpeedFvar* addTerm "high" (new LFuzzySet 500.0 1000.0 ?llf))
;; assert the first the fuzzy input -- temperature at 0.0
(assert (crispAirTemp 0.0))
(assert (airTemp (new FuzzyValue ?*airTempFvar* (new TriangleFuzzySet 0.0
0.0 0.0)))))
(defrule temp-cold-fanSpeed-low "if air temperature cold then set fan speed
low"
(airTemp ?t&:(fuzzy-match ?t "cold"))
=>
(assert (fanSpeed (new FuzzyValue ?*fanSpeedFvar* "low"))))
(defrule temp-OK-fanSpeed-medium "if air temperature OK then set fan speed
medium"
(airTemp ?t&:(fuzzy-match ?t "OK"))
=>
(assert (fanSpeed (new FuzzyValue ?*fanSpeedFvar* "medium"))))
(defrule temp-hot-fanSpeed-high "if air temperature hot then set fan speed
high"
(airTemp ?t&:(fuzzy-match ?t "hot"))
=>
(assert (fanSpeed (new FuzzyValue ?*fanSpeedFvar* "high"))))
(defrule control "printing of results and initiating next iteration"
;; to combine output of all 3 rules we must wait until the 3 rules
;; have all fired ... low salience for this rule achieves this
(declare (salience -100))
?catf <- (crispAirTemp ?t)
?fsf <- (fanSpeed ?fuzzyFanSpeed)
=>
;; defuzzify the fan speed fuzzy value and print out the result
(bind ?crispFanSpeed (?fuzzyFanSpeed momentDefuzzify)) (bind ?t (+ ?t 2.0))
(printout t "For temp = " ?t " Fan speed set to "?crispFanSpeed " RPM"
crlf)
(if (<= ?t 50.0) then
(retract ?catf ?fsf) (assert (crispAirTemp ?t))
(assert (airTemp (new FuzzyValue ?*airTempFvar* (new TriangleFuzzySet ?t ?t
?t))))))
