Please post your entire standalone-full.xml configuration. After that, please post your server output from the beginning of startup to your attempt to deploy your MDB. In particular, I am looking for log output from "org.hornetq.core.server" that contains "trying to deploy queue" or "Bound messaging object to jndi name".
It turned out that I have forgotten @JMSDestinationDefinition in one of the servlets.
