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.
