Hello Claus.
I'm not sure that I should change anything on the broker side : with
the same ActiveMQ, java applications with a similar connection factory
configuration (maximumRedeliveries=0) actually do a rollback on
failing messages processing, and the broker moves them to DLQ queues.
These applications are spring boot based applications with no XA.
I don't understand why without any exception handling in my camel
route, the message is processed only once, and, as it's managed with
"auto acknowledge" (default mode), a failing message is simply read
and lost. This is a suitable behavior for almost all our use cases,
but for some of them we'd need to save failing messages in DLQ.
Another idea ???
Thanks again.
Regards.
