    My problem about JMS & MDB !

    LeQuoc Thai Novice

      Hi all!
      I read about JMS and MDB inside "Mastering. EJB.4th.Edtion" (chapter 7). I use

      jboss-4.0.5.GA and EJB 3.0

      I writed a Message Driver Bean, look like:
      public class LogBean implements MessageListener {
       public LogBean() {
       System.out.println("LogBean created");
       }
       public void onMessage(Message msg) {
       if (msg instanceof TextMessage) {
       TextMessage tm = (TextMessage) msg;
       try {
       String text = tm.getText();
       System.out.println("Received new message : " + text);
       } catch (JMSException e) {
       e.printStackTrace();
       }
       }
       }
      
       public void remove() {
       System.out.println("LogBean destroyed.");
       }
      }

      And, I have ejb-jar.xml:
      ...
      <enterprise-beans>
       <message-driven>
       <ejb-name>LogBean</ejb-name>
       <ejb-class>mdb.com.LogBean</ejb-class>
       <messaging-type>javax.jms.MessageListener</messaging-type>
       <transaction-type>Bean</transaction-type>
       <message-destination-type>javax.jms.Topic</message-destination-type>
      
       <activation-config>
       <activation-config-property>
       <activation-config-property-name>destinationType</activation-config-property-name>
       <activation-config-property-value>javax.jms.Topic</activation-config-property-value>
       </activation-config-property>
       </activation-config>
       </message-driven>
      </enterprise-beans>

      But when I deploy it on JBoss server, I received some errors:
      org.jboss.deployment.DeploymentException: Required configproperty RequiredConfigPropertyMetaData@19238ad[name=destination descriptions=[DescriptionMetaData@147ff11[language=en]]] for messagingType 'javax.jms.MessageListener' not found in activation config [ActivationConfigProperty(destinationType=javax.jms.Topic)] ra=jboss.jca:service=RARDeployment,name='jms-ra.rar'
      ....

      I think that I must configure JBoss but I don't know where I do this ? Please guide to me or show me some documents about this problem.
      Thanks very much.
