Hi all. What I currently don't understand in this scenario: Why doesn't every Service uses its own WorkingMemory? Isn't that conceptually the same what you describe? And internal optimizations shouldn't be visible on the outside, right? Or what have I missed? Somehow it seems I don't see the big picture yet. Can somebody maybe give a short business example? Or maybe my knowledge of Drools Fusion is too limited, is there more info in the docs there? Thanks and cheers Bernd View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240418#...
