I will assume yes since you haven't specified. What do you mean "connection failure"? Does the client process crash? I will assume yes here too. anonymous wrote : | 3) Producer sends Message B | | Does the producer send message B before or after the non durable subscription is recreated? Please note that non durable subscriptions *do not survive* failure so any messages sent when they are non created (i.e. after the crash but before the recreation) will be *lost*. This is perfectly normal behaviour, see JMS spec for more details about differences between non durable and durable subscriptions.
