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.
