Hello Maciej.
Thank you for your helpful reply.

I have somequestions for confirming your remark.
Please teach me if my understanding is wrong.

1)Do you want to say "We can do jBPM clustering. And when we think about clustering, we have to care about StatefulKnolegeSession."?
About your last question, I will use StatefulKnolegeSession. And I will make this session instance when making the new flow.

The system which I want to make is human workflow system. A user submit a petition and other users check the petition.
So when user grant the petition, I expect changing the task status by using taskClient.

>From these your discription, I understood If I can controll the session and I can particular one session is loaded only in one server at that time, I can implement cluster model of jBPM. Is my understanding right?

2)Other than getting informations from DB(StatefulKnoledgeSession), I don't have to share informations between each server, right?
 From your discription, I think I don't have to.  But, I want to confirm.

Thanks and regards
