Hello XA transactions are your friend in this scenario.
Beware that the whole goal of leveraging a Message Broker is to decouple the producer from the consumer. In fact, when the producer sends the message, there may be a consumer there may be not, but if you've set the JMS delivery mode appropriately, the broker guarantees to attempt deliver the message once the consumer is online again. You should think of producer-broker and broker-consumer as transactional boundaries where a handover of responsibilities is occurring. The producer and consumer never interact directly. So you have two options: * Leverage XA transactions and delegate the responsibility of delivery to the broker (thus honouring the philosophy of async messaging). * Implement a custom mechanism for the consumer to send an ACK to the consumer, perhaps using JMS Reply To.
