Re: [rules-users] rules not wrking
You should read at least chapter 4 of
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/html/index.html
where eval() and everything else you can use in a rule is described.
Using output statements on the left hand side of a rule is not a very good
way of determining whether a rule fires or not. Using the
KnowledgeRuntimeLogger (see section 3.3.6) might be a better way of seeing
what goes on in your rule based system.
There is no special class for methods you can call in an eval(). An import
(in the .drl file) may be required if it is a static method. In any case, an
expression used inside eval() must result in a boolean value.

Re: [rules-users] rules not wrking
hi Esteban ,
My rule is something like this
rule "Area_EstimatedRval1_10-01-09_12-31-14"
date-effective "01-Oct-2009" date-expires "31-Dec-2014" salience 5
no-loop true
when
eval(BusinessLogic.gettest("inside Area_EstimatedRval1_10-01-09_12-31-14"))
objectP2483 : Para_2483( (fid2329=="Accessible Attic" ||fid2329=="Mobile
Home") && (fid2337=="Fiberglass (Blown)") );
then
System.out.println("Area_EstimatedRval1_10-01-09_12-31-14");
objectP2483.setFid2339(objectP2483.getFid2338() * 2.2);update(objectP2483);
end
but its not going inside the
BusinessLogic.gettest("inside Area_EstimatedRval1_10-01-09_12-31-14"))

Re: [rules-users] rules not wrking
Please remember that rules' conditions are evaluated when you
insert/modify/retract a Fact and not when you call fireAllRules().

Re: [rules-users] rules not wrking
If you really wanted to see your text string there, you might be able to
invoke a method that takes that text string and prints it and then
returns "true" in all cases. You'd most likely need to put it in an
Eval as suggested below.

Re: [rules-users] rules not wrking
You can't directly use java code inside the LHS of a rule. You can though
use eval to call a java method inside your LHS. Also remember that you don't
have to use ; in the patterns.
