[rules-users] build Drools packages

Hi, Could you please advice which is the best way to build Drools packages? I need to read the rules from database and I have to build drools packages. The content of the rules is very flexible : 1. I don't know the number of rules. 2. I don't know rule data: the type name, operation and value. 3. I do know the maximum number of types and operations the system support. How should I build the packages: Should I write component that will read the rules from database and will transform it to drl file? Any API I can use - Maybe BRMS API? I'm a ware of "rule templates" but I need a better generic way... Thanks, Meny
