I'm a newbie too, but I think you should just insert a
engine.executeCommand("(reset)");
before the run-command. Then the rule will fire. You find more about the
reset-command in Jess in Action section 6.1.1.

RE: JESS: new to jess
Hi Nirajkumar,
As the saying goes, "...you can't get there from here."
First, you'd be better off learning Jess from its command line scripting
environment, then move to programming the API when you have the basics
mastered.
In your example, you have a few things incorrect:
1. You need to use the Jess (reset) command before running the rule engine.
2. Only rules in the module having the focus will activate and fire,
provided that their left-hand side (LHS) patterns are satisfied. In this
case, your (test ...) fact is always TRUE, but you don't have the right-hand
side (RHS) doing anything (so you won't see any effect of the rule firing if
it did, other than what the (watch) command produces.
3. Use "eq" to compare symbols, objects, and references. Use plain vanilla
"=" for numbers. The danger is that you could write some code like:
(bind ?x 2)
(bind ?y 2.0)
(if (eq ?x ?y) then ...
expecting the condition to be TRUE, but it is really FALSE. Jess is
comparing both value AND type, and since an INT is never the same type as a
FLOAT, the condition is false. If you had said (= ?x ?y) then it would have
been TRUE. You can easily prove this yourself by running this program:
;; is-equal-or-not.clp
(clear)
(watch all)
(defrule is-equal-or-not
"Will always fire since it matches the (MAIN::initial-fact)"
=>
(bind ?x 2)
(bind ?y 2.0)
(printout t "x eq y :" (eq ?x ?y) crlf)
(printout t "x = y :" (= ?x ?y) crlf))
(reset)
(run)
Back to your example, I'd recommend this approach instead:
1. Copy this sample code below, and save it as test.clp in the same folder
as jess.jar or somewhere on Jess's CLASSPATH.
;; test.clp ;
(clear)
(defrule equality-test
(test (= 1 1))
=>
(printout t "equality test performed OK" crlf))
(reset)
(focus MAIN)
(run)
;;
2. Run it by typing (batch test.clp) at the Jess command line. You should
see something like:
Jess> (batch test.clp)
MAIN::equality-test: +1+1+2+t
==> Focus MAIN
==> f-0 (MAIN::initial-fact)
==> Activation: MAIN::equality-test : f-0,
FIRE 1 MAIN::equality-test f-0,
equality test performed OK
<== Focus MAIN
1
Jess>
My point is: Keep working many small examples like this until you are
comfortable with the Jess language, then try writing Java with the Jess API.
You'll learn Jess much better and more quickly.
Oh... and buy a copy of "Jess In Action"

Hi All,
I am new to using jess and was having some problems when i wrote a small java code...
when i do the following (below is part of the code), i donot get any fired rules, why
is that:
...

The system.out statement is printed but thw watch rules does not indicate that any

Sure -- the same way you might do it in Java, by using a little
class to represent the association. For example
public class Holder {
public double number;
public Object fact;
public Holder(Object o, double d) {
fact = o;
number = d;
}
}
Then in Jess
(store RESULT (new Holder ?b (/ ?mv ?io)))

Thank you ever so much.
One more quick question. In my rule I have calculated the following:
(/ ?mv ?io)
Is there anyway to save this along with the Fact reference in ?b ??

The things on the left-hand-side of a rule are always conditional
elements (patterns or groups of patterns), not function calls. Jess is
trying to interpret "(bind ?noncomp (/ ?mv ?io))" as a pattern that
matches "bind" facts, and it's complaining because (/ ?mv ?io) isn't a
valid slot value constraint.
There's no way to bind a variable on the LHS of a rule and see it on the
RHS of a rule other than by directly matching it. You're going to have
to compute (/ ?mv ?io) twice, once in the "test" CE and once on the RHS
of the rule.
I think, by the way, that you've done something else wrong here. Each of
the three bondMVMax patterns above can match a difference bondMVMax
fact. Since each one matches a different slot, I'm guessing you actually
mean for all the patterns to apply to the *same* fact; you're not trying
to find sets of three facts, but single facts that pass all these
criteria. You need to write all the criteria as one pattern:
(defrule calcifnc
(bondMVMax (cusip ?c)
(mv ?mv)
(issue_outstanding ?io&~nil))
(test (> (/ ?mv ?io) 10))
=>
(printout t ?c " is Non Complaint nc = " (/ ?mv ?io) crlf))

You can have the rule store a reference to the fact each time it
fires; for example , in your Java code
Rete engine = ...
ArrayList result = new ArrayList();
engine.store("RESULT", result);
Then make the rule look like
(defrule calcifnc
?b <- (bondMVMax (cusip ?c)
(mv ?mv)
(issue_outstanding ?io&~nil))
(test (> (/ ?mv ?io) 10))
=>
(printout t ?c " is Non Complaint nc = " (/ ?mv ?io) crlf)
((fetch RESULT) add ?b))
After running the engine, the ArrayList "result" will contain
references to all the jess.Fact objects that match the criteria.

Jess treats Java objects as typeless, so really I'd be surprised if you had any problem working with generics right now. Enums are basicvally just syntactic sugar over classes, so it's quite likely that you'll be able to do what you need to do with them, as well (although there may be a bit of hackery with names involved that Jess could help by abtracting away.) Speaking of which, I understand that inner classes in 1.5 don't use the old "$" naming convention anymore, which could break Jess language code that assumes it (it will also break reflective Java code that assumes it as well; I don't understand their rationale for making this change.) - Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National LabsFAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)

RE: JESS: Newbie questions
Thanks a million.
Any suggestions on my second question?
I need to save all the details for each fact which passes the test into
a data structure.
This I need to pass back to my java code, which in turn can save the
results to a db.
What would be the best way of doing this?
