I believe all your requests are in 4.0, give that a try. For 2.0.6
you'll have to unwrap

Hi All,
I am using Drools 3.0.6 and unable to perform some simple form of
multiplication. I want to compare an object field with another field
multiplied by a factor.
*
rule
* "*Calculate* Business profit,1"
*when
**EMIAgainstProperty* ( bp1 : businessProfit1 )
emi : *EMIAgainstProperty* ( businessProfit2 > *(bp1*1.5)* ) *then
*emi.setBusinessProfit((emi.getBusinessProfit1()+emi.getBusinessProfit2())/2);*
**end*
I get an error on creation of the package that * is undefined for
Double and double. I understand this is because Drools does an auto
box on primitive type variables. But is there a work around to do
simpler comparisons like this, especially on the right hand side of
the condition. some thing like [ variable * constantValue ].
Also, i am forced to do a declaration for businessProfit1, and use in
the comparison below. I am not able to compare two fields of the same
object directly.
some thing like businessProfit2 > businessProfit1 does not work, why
is this so? Any one has faced these problems earlier?
Thanks
Natraj
