17.6.5. Configure Dead Letter Addresses

Introduction

A dead letter address is defined in the <address-setting> element of the Java Messaging Service (JMS) subsystem configuration. 

<!-- undelivered messages in exampleQueue will be sent to the dead letter address 
deadLetterQueue after 3 unsuccessful delivery attempts
-->
<address-setting match="jms.queue.exampleQueue">
  <dead-letter-address>jms.queue.deadLetterQueue</dead-letter-address>
  <max-delivery-attempts>3</max-delivery-attempts>
</address-setting>
If a <dead-letter-address> is not specified, messages are removed after trying to deliver <max-delivery-attempts> times. By default, messages delivery is attempted 10 times. Setting <max-delivery-attempts> to -1 allows infinite redelivery attempts. For example, a dead letter can be set globally for a set of matching addresses and you can set <max-delivery-attempts> to -1 for a specific address setting to allow infinite redelivery attempts only for this address. Address wildcards can also be used to configure dead letter settings for a set of addresses.
