Thank's for your sugession of using "not in" instead of "not" but my
problem is that "not" can also come without "in".
Actually I am making a generator of rule file from expression like
((NOT (ENDS WITH (G10.2, ",")))
((NOT (G13.1 IN ("1","2","3"))) OR (G250.8 = Y)))
Where G13.2, G250.8, G10.2 are variables coming from a map inserted in
working memory.
I am accessing these variables from map.
My rules are as follows
This rule is working fine.
rule "Editable_G10.3"
when
((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19)))
then
System.out.println("comming
here----------------------------------------------------->");
End
This is not working
rule "Mandatory_G10.3"
when
(not((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))))
Then
System.out.println("comming
here----------------------------------------------------->");
End
In also tried following approaches:
1) eval(not((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))))
2) eval(!((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))))
But in both cases it is giving same error:
org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule
name=ValidationRuleExp_G10.3, agendaGroup=MAIN, salience=0,
no-loop=false]
com/telekurs/nva/mde/fe/ak/validation/Rule_ValidationRuleExp_G10_3_0.jav
a (11:495) : Cannot use this in a static context
com/telekurs/nva/mde/fe/ak/validation/Rule_ValidationRuleExp_G10_3_0.jav
a (11:500) : Type mismatch: cannot convert from String to int
I am trying to find out some general concept so that I can change just
achieve the functionality of not.
Thanks
Gaurav

Subject: Re: [rules-users] How to use not operator in drool.
Remove your "eval" and use "or" instead of "||" for the OR CE.
Although, I feel that this is not what you want... what you want is
simply:
when
Map( this['city'] not in ( "mumbai", "delhi" ) )
then
//...
end

2007/9/12, Gaurav2007 <[EMAIL PROTECTED]>:
Hi ALL,
I am using drool4.0.1 in my application i am able to use IN,OR,AND
operator
but i am facing problem in using not operator.
my requirement of not operator is just like a not gate.
the way i am using it is :
eval(not((Map( this["city"] !="mumbai"))||(Map( this["city"]
=="delhi"))))
so can you please help me out to solve this problem:
should i use not operator or some thing else in drool.
Thanks,
