Chapter 21. Configuring Message Driven Beans through deployment descriptors

You configure properties by using the <message-driven> element and sub elements which correspond to the @ActivationConfigProperty annotation.

ejb-jar.xml:

			
<message-driven>
	<ejb-name>ExampleMDB</ejb-name>
	<ejb-class>org.jboss.tutorial.mdb_deployment_descriptor.bean.ExampleMDB</ejb-class>
     <transaction-type>Bean</transaction-type>
     <message-destination-type>javax.jms.Queue</message-destination-type>
   <activation-config>
      <activation-config-property>
      	<activation-config-property-name>acknowledgeMode</activation-config-property-name>
      	<activation-config-property-value>AUTO_ACKNOWLEDGE</activation-config-property-value>
      </activation-config-property>
    </activation-config>

</message-driven>

jboss.xml

			
<message-driven>
   <ejb-name>ExampleMDB</ejb-name>
   <destination-jndi-name>queue/tutorial/example</destination-jndi-name>
</message-driven>

The queue/tutorial/example is configured through the queue-example-service.xml
