Thanks for trying it out. Actually it was a typo in my posting text and not in the code. I have declared variable called tText and have a getTText() method. Below is the rule segment. rule "entity.testrule" when $rulesSerivceTest:RulesServiceTest(tText:tText) then logger.info("Received an Test"); end Below is the error while creating the package. [java] java.lang.RuntimeException: Unable to create Field Extractor for 'tText' : [Rule name=entity.testrule, agendaGroup=MAIN, salience=0, no-loop=false] [java] org.drools.RuntimeDroolsException: org.drools.RuntimeDroolsException: Field/method 'tText' not found for class 'com.satmetrix.rules.test.rulestest.RulesServiceTest' [java] 16:24:57,642 INFO - Error Summary : Unable to create Field Extractor for 'tText' : [Rule name=entity.testrule, agendaGroup=MAIN, salience=0, no-loop=false] I was using 4.0.4 then I tried with 4.0.7 and got the same error. Are you extracting the field in the rule?

I'm working with Drools 4.0.7 and if I set up a test case with the values as you describe (String tText, ...), my test runs successfully. Stupid question: Are you sure that you have no typo in your rule? You get an error for "sText", but you have declared "tText".
