dead letter queue

Hello,

I would like to know if when I send a message on queue which does not exist
in my ActiveMQ broker where are stored this messages ? Is there any dead
letter queue in ActiveMQ ? How do I configure it ?

Thanks

In addition to James' comments please note, that the default dead  
letter strategy only
sends messages to the dead letter queue if the messages are sent  
persistently.
You can overwrite that behavior by configuring the deadLetterStrategy  
setting
the processNonPersistent property to true.

Best regards
Andreas

ActiveMQ creates destinations on the fly by default...

DLQs are only used when consumers fail to process messages a given
number of times
