After changing my default datasource, during the deployment of my message-driven beans, I get the following exception:

16:45:51,781 WARN  [JMSContainerInvoker] JMS provider failure detected for MDB

As explained here, in the JBossMQ loging module, you should change the dsJndiName attribute to point to a valid datasource.

Also, very important, you should make sure to prepend the jndi name with "java:/". The following attribute is INVALID.

   <module-option name = "dsJndiName">jdbc/WhateverDS</module-option>

How to debug

In conf/log4j.xml, enabled TRACE logging for the following category:

   <category name="org.jboss.security.plugins.JaasSecurityManager.jbossmq">
     <priority value="TRACE" class="org.jboss.logging.XLevel"></priority>
   </category>

You should then get this TRACE output:

  2006-08-29 16:45:51,406 TRACE [org.jboss.security.plugins.JaasSecurityManager.jbossmq] Begin isValid, principal:null, cache info: null
  2006-08-29 16:45:51,406 TRACE [org.jboss.security.plugins.JaasSecurityManager.jbossmq] defaultLogin, principal=null
  2006-08-29 16:45:51,421 TRACE [org.jboss.security.plugins.JaasSecurityManager.jbossmq] Login failure
javax.security.auth.login.LoginException: Error looking up DataSource from: DefaultDS
