Re: [rules-users] DRL authoring help

Hi Krishnan, I need the functionality of being able to call methods of a global class in the 'then' piece of the drl. I had defined the drl file as: package test.tools.rulesengine import test.tools.rulesengine.Utilities; global test.tools.rulesengine.Utilities util; rule "Rule1"................. When I debug the 'when' piece, I see that the method to check the name is being called, but tfter that, the global util's class method is not called. Any pointers would be helpful. Thanks, Smitha Krishnan <krishiyer(a)gmail.com&gt; wrote: Hi Smitha, Rewrite the rule as follows :- rule "Rule1" when $Position1 : Position ( name matches "POS-RPT_0_1" ) then $Position.setColor("red"); end Note : You had something called util, unless it is a global, it will not work. -Krishnan.

I have a .drl as given below: rule "Rule1" when $Position1 : Position() eval($Position1.getName() contains "POS-RPT_0_1") then util.setColor($Position1, "red"); end Before firing the rules, I assert my object as posIn = new Position(name, id, symbolCode, lonDouble, latDouble, elevDouble, reportDate, this); workingMemory.assertObject ( posIn ); workingMemory.fireAllRules(); I get the following error. org.drools.rule.InvalidRulePackage: Rule Compilation error The left-hand side of an assignment must be a variable Syntax error on token "contains", invalid AssignmentOperator at org.drools.rule.Package.checkValidity(Unknown Source) at org.drools.common.AbstractRuleBase.addPackage(Unknown Source) What is wrong with my drl? I have a Utilities class that I have defined as global. Thanks --------------------------------- Looking for a deal? Find great prices on flights and hotels with Yahoo!
