Unfortunately something goes wrong because when one server is online the application run correctly. When the second server enter in the cluster it's unable to reach the MDBs defined in the master node. Every time I've got the exception *javax.naming.NameNotFoundException: queue not bound.* As the guide said I left untouched the *jndi.properties* and I've changed the each jboss.xml as the follows: <jboss>    <enterprise-beans>       <message-driven>          <ejb-name>Engine</ejb-name>          <resource-ref> *             <res-ref-name>queue/Engine</res-ref-name>* *             <jndi-name>jnp://localhost:1100/queue/Engine</jndi-name>*          </resource-ref>       </message-driven>    </enterprise-beans>    <resource-managers>    </resource-managers> </jboss> and each ejb-jar.xml as the follows: <ejb-jar >    <description><![CDATA[No Description.]]></description>    <display-name>Engine</display-name>    <enterprise-beans>       <message-driven >          <description><![CDATA[Bean to access messages]]></description>          <display-name>Engine</display-name> *         <ejb-name>Engine</ejb-name>* *         <ejb-class>com.web.ejb.engine.EngineBean</ejb-class>*          <transaction-type>Bean</transaction-type>          <acknowledge-mode>Auto-acknowledge</acknowledge-mode>          <message-driven-destination> *            <destination-type>javax.jms.Queue</destination-type>*          </message-driven-destination>          <resource-ref> *             <res-type>javax.jms.Queue</res-type>* *             <res-ref-name>queue/Engine</res-ref-name>* *             <res-auth>Container</res-auth>*          </resource-ref>       </message-driven>    </enterprise-beans>    </assembly-descriptor> </ejb-jar> I've tried to query the service *JNDIView* in jmx-console and HA-JNDI Namespace is still empty. Have somebody got any idea? Thanks a lot for your attention.
