Hi Srinivas, I would look at the newly released 5.01 GA, specifically at the documentation for Fusion, which focuses on event processing. | Jonathan Ingold | ________________________________ From: Srinivas Doddi [mailto:Srinivas_Doddi@gap.com] Sent: Tuesday, May 26, 2009 11:41 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] Rules Effective Date Hi I am a newbie for Drools and googled for a good time. I would like to know if Drools 4.0.7 and Drools 5 have anything like an "Effective Date" concept? We have a requirement for having a rule written by the Business Analysts and takes effective for a future date, without restarting the application. Is Rules Engine intelligent enough to pick the rules depending on effective dates? Thanks a lot for your help. SRINI
