JMS message redelivery on exception in JMS listener

Question

Javadoc for org.springframework.jms.listener.AbstractMessageListenerContainer states, that if

\"sessionAcknowledgeMode\" set to \"CLIENT_

Answer 1

It depends on which listener container you use; when using AUTO ack mode, the SimpleMessageListenerContainer acks after the listener returns (i.e. a traditional JMS MessageListener). The DefaultMessageListenerContainer acks before the listener is invoked, so you need acknowledgeMode="transacted" to prevent message loss.

The javadocs in this area were a bit misleading and have been improved recently.

With CLIENT_ACKNOWLEDGE, you're on your own to do the acks. That doc just means you are at the whim of the broker. According to the JMS message javadoc:

Messages that have been received but not acknowledged may be redelivered

In my experience it is best to use auto ack with an SMLC and transactions with DMLC.
