    EntityManager in a @Service

    Andrea Polci Newbie

      I'm trying to write a @Service that need access to an EntityManager.

      I'll use the service throw the JMX console.

       

      The problem is that I can't find a way to inject the entity manager into the service.

       

      This is a simplified version of my code:

       

      @Management
      public inteface MyManager {
         public void method(String argument);
      }
      
      @Service(objectName="xxxx:service=myservice")
      public class MyMBean implements MyManager {
      
        @PersistenceContext(unitName="my-persistence-unit")
        private EntityManager em;
      
        public void method(String argument) {
          // code using em
        }
      }
      

       

       

      The service get exposed throgh the jmx console, but em is always null.

       

      I tried to @Inject an entity manager configured in a @Producer, but i get the same result.

       

      I'm using JBoss AS 6.0.0 Final

       

      Thanks for any help,

      Andrea
