I want to adjust message priority in a queue accessed through REST. I can only find 'JMSPriority' for the JMS interface.
I'm not 100% clear on your use-case here. Are you trying to set the priority on the JMS message that you're sending via REST? If so, see http://docs.jboss.org/hornetq/2.3.0.Final/docs/user-manual/html_single/index.html#d0e12719.
