[rules-users] About drools

Hi , I am new to drools. We are using drools with java in our project. We are doing leave application system. we created some rules and they are working undre java. But actually problem is we are facing is, we developed this ok, if user want to change the rule then where he enter the new rule and how it works. we have to give user the drl file or any other. But the user dont know the drl file and he want to change only rules but he dont know the drl file how can he enter new rules. Regards: Kranthi dalai
