I am new to drools and even more new to Guvnor. I have a below code with simple rules (just 2) which doesn't work as expected, any help would be greatly appreciated. I attempted to copy the contents of guvnor generated drl file to a local drl file and tested with drools expert, it works well. For the below program, Drools expert (minor changes to java program - ResourceFactory.newClassPathResource("test.drl")) show the s.o.p (after firing 1st rule) and prints 90000 (after firing 2nd rule) as expected. Drools guvnor prints salary as 0.0. Not sure what is going wrong while integrating with Guvnor, doesn't work as expected. need help!
