Hello, can someone tell me what's the advantage of using Environments for StatefulSessions? An Example: this.ksession = kbase.newStatefulKnowledgeSession(this.ksessionConfig, environment); vs. this.ksession = kbase.newStatefulKnowledgeSession(this.ksessionConfig, null); Are Globals or other Objects (e.g. Session-ID's) shared within/depending on the Environment? Because that will be problematic in my Application. Actually i'm using Environments, but they aren't serializable which is why I have to check if I really need them. Kind regards, O.S. Furthermore: I don't need the JPA-Persistence functionality.
