Re: [rules-users] Sir, Seekin your's Help on Drool
Hi Thnks for writing to me. I am new to this forum.I have indeed noted down your suggestion and I wll definitely act on it. I have gone thru the documentations and few books and have been trying hard to lean and implement since I have to deliver it as well. I could not find the solution after trying hard. So have to put it here desperately. Sorry again if I have broken the norms. Regards San ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Sir, Seekin your's Help on Drool
pp:PremiumCalculatorFormBean (fact in this case) contains 2 int fields age
and premiumPaymentTerm.
I need to validate (age+premiumPaymentTerm) sud nt b 70.
So in 1st condition column i am calling a method
int getMaturityAge(pp) {
int maturityAge=0;
int age=0;
int premiumPaymentTerm=0;
maturityAge=age+premiumPaymentTerm;
return maturityAge;
}
In the condition I write, maturityAge(pp) $1 and provide 70 as the
param value.
Nw the error that I am gettin...
1) while writing the above condition , it is unable to resolve pp.
no viable alternative at input 'pp' in rule MaturityAge
Validation_38
2) for testing purpose I call this method without any argument and returning
90.
In his case also I am getting
...no viable alternative at input ')' in rule MaturityAge
Validation_38
...mismatched input '' expecting ')' in rule MaturityAge
Validation_38
In Action part I have put System.out.println(Maturity value sud be less
than 70 )

Re: [rules-users] Sir, Seekin your's Help on Drool
You said that you will stick to the norms here but you do the opposite in your post : Where are the rules ? As far I can guess from all you wrote so far, the errors you have are all easily fixable by reading the very basis of drools doc, like what is a field constraint, how to specify it and how it is transformed (this will explain why your maturityAge(pp) $1 has no chance to work). The errors mismatched input or cannot find ... are basic errors that are theorically fixed as soon as you have the DRL under your eyes... If you have read the doc, you know that a decision table is a way to write rules templates, and it finally generates some DRL (the only executable format for drools). Decision table design and debug cannot be done without a close analysis of produced drl code. The consequence of that is if you can't write a simple DRL that do the job, you won't be able to do the same with a decision table. So, start by getting the generated DRL, fix it, then go back to your decision table and fix it accordingly. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Sir, Seekin your's Help on Drool
As the others have stated, without some actual rules it is very difficult, if
not near impossible to provide help.
Inferring what you might be trying to do, here is an example of what I *think*
you are trying to do:
CONDITION
$pp: PremiumCalculatorFormBean ( )
$maturity: Integer ( ) from getMaturityAge($pp)
eval ( $maturity 70 )
For this to work, you should change your Drools function to return Integer
object.
Drawing further assumptions form your function, which is always going to return
0 as you have it written here, I will assume that age and premiumPaymentTerm
are properties of PremiumCalculatorForBean class, you could do the same this
without the function call like this:
CONDITION
PremiumCalculatorFormBean ( $age: age, $term : premiumPaymentTerm)
eval ( ($age + $term) 70 )
or
CONDITION
$pp: PremiumCalculatorFormBean ( )
eval ( ($pp.age + $pp.premiumPaymentTerm) 70 )
the difference is really just preference, and personal style.
In the first example you capture the age and term into separate variable, and
then you perform the math on those two varaibles. In the second pp is
capturing the PremiumCaclulatorFormBean object and the math is done on
properties of that object.
In both examples, if you have two PremiumCalculatorFormBean objects in working
memory, then this rule will fire twice, unless you use some control mechanism
to force them to only fire once.
I hope this helps. I suspect it may be on the right track, or at least let you
see the proper syntax for define the LHS conditional constraints.
