How to increase the number of MDB instances listening to a JMS Queue in Jboss 4

For example, as we configure the number of MDB instances listening to a JMS Queue in ejb 3 as given below,

@ActivationConfigProperty( propertyName = "maxSession", propertyValue = "someNumber")

I want to know how it can be done in EJB 2.1 Jboss 4.

Currently i use xDoclet for generating the ejb-jar.xml for the MDB and my current declaration is as follows.

 * <!-- begin-xdoclet-definition -->
 * @ejb.bean name="myEjb"
 *     acknowledge-mode="Auto-acknowledge"
 *     destination-type="javax.jms.Queue"
 * what to use for max Session??

this results in activation configs in ejb-jar.xml as follows

 <activation-config>
           <activation-config-property>
             <activation-config-property-name>destinationType</activation-config-property-name>
             <activation-config-property-value>javax.jms.Queue</activation-config-property-value>
           </activation-config-property>
           <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>

The syntax that you have should work fine. If that is not working, I would suspect that you have a deployment descriptor file in your META-INF directory that is over riding the maxSession value.

Or, conversely, if the maxSession annotation is not being honored, you may have to use a deployment descriptor file, such as an ejb-jar.xml file.

According to xdoclet doc:

* @ejb.activation-config-property
*     name="maxSession"
*     value="someNumber"
