The messaging subsystem in Wildfly is enabled in the standalone-full.xml config (not standalone.xml).
To add a new queue, search for <subsystem xmlns=”urn:jboss:domain:messaging:2.0″>, and then within the <hornetq-server> section, add a new <jms-destinations> if it doesn’t exist already, and define your queue name and JNDI lookup:
<jms-destinations>
<jms-queue name="exampleQueue">
<entry name="jms/queue/example"/>
<entry name="java:jboss/exported/jms/queue/example"/>
</jms-queue>
</jms-destinations>
