Looking back in the thread, here's that do-extract deffunction:
statement = "(deffunction do-extract (?
rand) "+
"(?rand extractRoots))";
and back to your original message, here's the declaration of
extractRoots:
public void extractRoots(Integer primeRoot)
So the error is because your do-extract deffunction wasn't passing any
argument when it called extractRoots, but that method requires one.

Hi Ernest,
Wow an email from the man himself! :) Thanks for responding! I had
to change your version on the last line to this:
statement = "(defrule modulus"+divisor+
" (RandomNumber (value ?x) (OBJECT ?a))" +
" (test (eq 0 (mod ?x "+divisor+")))"+
"=>"+
"(call ?a extractRoots "+divisor+"))"; <---- HERE
Just to let you know... Your version:
=======
statement = "(defrule modulus"+divisor+
" (RandomNumber (value ?x) (OBJECT ?a))" +
" (test (eq 0 (mod ?x "+divisor+")))"+
"=>"+
"(do-extract ?a))";
=======
gave me the following message:
Jess reported an error in routine call
while executing (call ?rand extractRoots)
while executing deffunction do-extract
while executing (do-extract ?a)
while executing defrule MAIN::modulus223.
Message: No overloading of method 'extractRoots' in class
RandomNumber I can call with these arguments: (call ?rand
extractRoots).
Not sure why?
Thanks,
David
