Hi all, Can somebody help me here?? I've a business rule presented in bold here that I've put in the DRL file in the simplest form but compilation of rule is generating this error "line 6:342 required (...)+ loop did not match anything at character ' '" And any set of value is getting evaluated to TRUE.....that means rule validation is not happening.....I understand that I can use helper function in java classes and call them in the rule but wanted to know how can I do the same entirely in DRL file OR what's wrong with this. I've spent entire day to figure out but completely clueless and afraid to try function approach due to project deadline. Plz help. pers: Person(sourceType == 'Insurance' && (age != null && > 17) && ((cholesterol !=null && >= 200) || (hdlCholesterol !=null && < 60) || (cholesterolToHdlRation !=null && > 4.5) || (ldlCholesterol !=null && >160) || (vldl !=null && > 40) || (triglyceride !=null && > 50) || (glucose !=null && >130) || (bmi !=null && >=25) || (bodyFat > 0. 25 && sbjGdrCd !=null && == 'F' && age !=null && > 17 && < 40) || (bodyFat > 0.30 && sbjGdrCd !=null && == 'F' && age !=null && > 39 && < 60) || (bodyFat > 0.31) && sbjGdrCd !=null && == 'F' && age !=null && age > 60) || (bodyFat > 0.19 && sbjGdrCd !=null && == 'M' && age !=null && >17 && < 40) || (bodyFat > 0.23 && sbjGdrCd !=null && == 'M' && age !=null && age > 39 < 60) || (bodyFat > 0.24 && sbjGdrCd !=null && == 'M' && age !=null && >=60))) //Age>=18 AND Total Cholesterol >=200 OR HDL <60 OR Cholesterol Ratio >4.5 OR LDL >160 OR VLDL >40 OR Triglycerides >150 OR Glucose >130 OR BMI >=25 OR Body Fat % greater than the range of 14% and 25% when gender = F and age between or equal to 18 and 39 OR Body Fate % greater than the range of 18% and 30% when gender = F and age between or equal to 40 and 59 OR Body Fat % greater than the range of 21% and 31% when gender = F and age >60 OR Body Fat % greater than the range of 7% and 19% when gender = M and age between or equal to 18 and 39 OR Body Fat % greater than the range of 14% and 23% when gender = M and age between or equal to 40 and 59 OR Body Fat % greater than the range of 15% and 24% when gender = M and age >60 -- View this message in context: http://www.nabble.com/What%27s-wrong-with-the-connectives--tp20571531p205...

Thanks Edson for the reply but it didn't work. First off, I want to do a null check for age and return false if age or any variable is null. Secondly, I tried that "," connective but didn't work either and counted again..... there is no extra () pair. Actually the business rule here is sourceType=='Insurance' && age!=null && >17 and after that if any of the bracketted value surrounded by the ( ) validates to true then, rule should validate to TRUE. So, the simplified rules is: sourceType=='Insurance' && (age not null && >17) AND ANY OF FOLLOWING TRUE...(validation1) || (validation2) || (validation3)...and so on. that's why I had put another () to surround the set of validations starting from cholesterol. Also, what is this error about?? line 6:342 required (...)+ loop did not match anything at character ' ' I think this is bcoz rule is not getting parsed properly by antlr grammer..but I'm not able to see...where the mistake is. Also, I noticed while debugging that person object which I'm inserting in working memory ...retains the previous value...even when I'm changing the values of its variables.....why is that? Plz people take a look n point out the mistake here.
