Hi all, First time trying to learn JBoss Rules here. We have a pretty large database (DBMS), we want to build some rules and retrieve data based on the rules. Could someone give a hint or an example of this usage scenario? I mean, how can I use rules for database query, without writing my rules in SQL directly? We are currently writing everything in HQL (Hibernate), but the rules change every 3 months on average, so that's not a way to maintain the system. Therefore, we want to extract that portion of the business logic out of the code. The data structure does not change, but the rules keep on changing. I'm reading the user's guide, running thru the examples, writing some of my own, but still no clue how to make it work with database. If someone could give a sample, that would be greatly appreciated. Thanks a lot. --------------------------------- Bored stiff? Loosen up... Download and play hundreds of games for free on Yahoo!
