    How to inject MessageContext for MDBs?

      When I deploy (AS 7.0.1) a EJB-JAR containing only a MessageDriven Bean it will not be able to inject the MessageDrivenContext. Looks like the type is not known:

       

      03:03:46,989 WARN  [org.jboss.as.ee.component.ResourceInjectionAnnotationParsingProcessor] (MSC service thread 1-1) Can'

      t handle @Resource for ENC name: net.eckenfels.as7example.ejb3mdb.ejbjar.EJB3MDB/mdc on class net.eckenfels.as7example.e

      jb3mdb.ejbjar.EJB3MDB since it's missing a "lookup" (or "mappedName") value and isn't of any known type

       

      The code looks like:

       

      {code}
      package net.eckenfels.as7example.ejb3mdb.ejbjar;
        
      import javax.annotation.PostConstruct;
      import javax.annotation.PreDestroy;
      import javax.annotation.Resource;
      import javax.ejb.ActivationConfigProperty;
      import javax.ejb.MessageDriven;
      import javax.ejb.MessageDrivenContext;
      import javax.jms.JMSException;
      import javax.jms.Message;
      import javax.jms.MessageListener;
      import javax.sql.DataSource;
       
       
      @MessageDriven(name = "EJB3MDB", activationConfig = {
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
        @ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/MyQueue"),
        @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge")})
      public class EJB3MDB implements MessageListener
      {
          private DataSource dataSource;
          
          @Resource
          MessageDrivenContext mdc;
       
          @Resource(mappedName = "java:jboss/datasources/ExampleDS")
          public void setDataSource(DataSource dataSource)
          {
              this.dataSource = dataSource;
          }
       
          @PostConstruct
          public void initialize()
          {
       ...
          }
       
          @PreDestroy
          public void cleanup()
          {
      ...
          }
       
          public void onMessage(Message message)
          {
      ...
          }
      }
      {code}
