Can we use ejb-jar.xml instead of annotations for MessageDrivenBean(MDB) in EJB 3.0?

I\'ve configured the message destination type, name etc using @ActivationConfigProperty in EJB 3.0 but I wanted to configure the MDB using deployme

    Below is the xml content for configuring MDB, can modify the below code accordingly.

    <enterprise-beans>
        <message-driven>
            <ejb-name>SomeMessageBean</ejb-name>
            <ejb-class>
                com.bean.SomeMessageBean
            </ejb-class>
            <messaging-type>javax.jms.MessageListener</messaging-type>
            <transaction-type>Container</transaction-type>
            <message-destination-type>
                javax.jms.Queue
            </message-destination-type>
            <activation-config>
                <activation-property>
                    <activation-config-property-name>destinationType
                    </activation-config-property-name>
                    <activation-config-property-value>javax.jms.Queue
                    </activation-config-property-value>
                </activation-property>
                <activation-property>
                    <activation-config-property-name>messageSelector
                    </activation-config-property-name>
                    <activation-config-property-value>MessageFormat = 'Version 3.4'
                    </activation-config-property-value>
                </activation-property>
                <activation-property>

                    </activation-config-property-value>
                </activation-property>
            </activation-config>

                        </resource-type>
                            <res-auth>Container</res-auth>

                                <injection-target-name>datasource</injection-target-name>
                            </injection-target>

        </message-driven>
    </enterprise-beans>

    Thanks man, but I've figured it out in a much simpler way. Below is the code

    <ejb-jar id="ejb-jar_ID" version="3.1"
          xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                              http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd">
    
      <display-name>SampleTransactionMDB</display-name>
      <enterprise-beans>
        <message-driven>
          <display-name>SampleTransactionMDB</display-name>
          <ejb-name>SampleTransactionMDB</ejb-name>
          <ejb-class>com.example.SampleTransactionMDB</ejb-class>
          <transaction-type>Container</transaction-type>
          <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>destination</activation-config-property-name>
              <activation-config-property-value>/queue/SampleTransactionQueue</activation-config-property-value>
            </activation-config-property> 
          </activation-config>
        </message-driven>  
      </enterprise-beans>
      <assembly-descriptor>
      </assembly-descriptor>
    </ejb-jar>
