Hi, I am trying to upgrade a system from Drools 4.0.7 to Drools 5.0.1 to use Drools Fusion temporal operators. With used to start our rule engine this way: RuleBase ruleBase = RuleBaseFactory.newRuleBase(new RuleBaseConfiguration(ourClassloader)); WorkingMemory workingMemory = ruleBase.newStatefulSession(); Now this seems deprecated reading the Drools fusion documentation... Should I give up RuleBase for KnowledgeBase to be able to start the rule engine in "Stream" event processing mode ? Thanks for your help !
