Subject Re: ActiveMQ redelivering acknowledged messages
Date Mon, 03 Nov 2014 18:17:28 GMT
My main suggestion is to make CERTAIN all your settings are correct. JMS is
a difficult API and it’s possible to easily make mistakes and shoot
yourself in the foot.

Every time I think something is wrong it’s because I was accidentally using
the API wrong.
