Is it possible to have dead letter queue for individual queues

Question

I currently have a Queue in my ActiveMQ server called hello.world. Whenever a message fails to be processed, ActiveMQ creates a default directory called Activ

The thing you are looking for is called Individual Dead letter Queue strategy, in this process ActiveMQ creates specific DLQ for each queue/topic,

you can implement it as follows, by tweaking your activemq.xml a bit

 <destinationPolicy>
    <policyMap>
      <policyEntries>
       <policyEntry queue=">">  <!-- '>' is the wildcard used in ActiveMQ which means for all queues, i.e. same as '*' in any other language -->
        <!-- need to add the following lines in you conf file -->
          <deadLetterStrategy>
            <individualDeadLetterStrategy
              queuePrefix="DLQ." useQueueForQueueMessages="true" />
          </deadLetterStrategy>
        </policyEntry>
      </policyEntries>
    </policyMap>
  </destinationPolicy>

this configuration will create DLQ with names like DLQ.<queue_name> , if you do not want the prefix , you can remove queuePrefix attribute.

hope this helps!

Good luck!
