-----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users- bounces(a)lists.jboss.org] On Behalf Of Wolfgang Laun Sent: 05 February 2012 12:22 To: Rules Users List Cc: Rules Dev List Subject: Re: [rules-users] How to write rules in two fact's fields? In most programming languages the result of (e.g.) an integer comparison 20 <= price is a value of a different type, i.e., boolean, with values "true" or "false". (You have heard this at some time, right?) Consequently, the comparison of a boolean with an integer true < 30 depends on whether the language tolerates it, and if so, how that result is defined. IT IS A BUG THAT DROOLS TOLERATES (BUT DOES NOT DEFINE) SUCH "MULTIPLE" COMPARISONS BUT DOES NOT FLAG THEM AS AN ERROR OR IMPLEMENT THEM IN SOME WAY. (Tested with 5.3.0 Final.) This means that you'll have to rwrite your constraints using && or ||, as appropriate. -W On 05/02/2012, shanmuga <shanmugasundaram.t.v(a)gmail.com&gt; wrote: > Hi, > I want to know, how to write rules in two fact's fields? > > I used two facts, it will take AND condition or OR condition in > between the two facts. > > Please check my code.... > > package Project > import com.sample.Person; > import com.sample.Price; > > rule "rule_Name" > when > per:*Person*(50 <= age < 100, 10000 <= income < 50000, > occupation == "Business", category == "Military", location == > "Bangalore", custype == > "Individual") > pri:*Price*((20 <= price < 30) || price == 1) > then > System.out.println("Success"); > end > > > The both fact values are satisfy means, what is the output? > > I got output, even the *Price* fact's value is wrong.
