All, OK, in my current 2.1 version of my app, I have 8 different rules files that have different sets of rules. In looking at 3.0.5 [and maybe this existed previously, but I missed it], there is a method on PackageBuilder called addPackageFromDrl. Can I load all the individual sets into 1 rule package? Then Drools will determine which rules to fire based upon what objects are asserted into working memory? The reason I came to this is I was looking at the Spring integration and was wondering if I should have 1 RuleBased of the 8 individual ones like I have today. Thoughts and Suggestion Welcome! Ron
