I have looked at Drools rule engine but it stores all the rule info in xml/drl files..we intend on runing the appl on weblogic multiple/clustered servers. I am wondering that if we modify the rules at runtime all servers instances will not pick up the changes from the xml/drl files..Does anyone has a solution for it or am i just getting paranoid about nothing..
I haven’t used any rule engine yet but this is my guess how they factions.
When you start your application, all rules that you defined in rule engine will go in application scope. And for all requests it will take rule from the application scope. If your rule engine support change in rules without restarting application server, and your clustering solution replicate change in application scope to all server on real-time basis, then and then only your life will be easy.
