从另一个ear交叉引用实体

@Entity
public class Car {
//...
}

@Stateless
public class CarDao implements CarDaoRemote {
   @PersistenceContext( unitName = "carPersistenceUnit" )
   private EntityManger em;

   public void storeCar( Car car ) {
      em.persist( car );
   }

   public Car findCar( Car car ) {
     return em.find( Car.class, car.getID );
   }
}

@Remote
public interface CarDaoRemote {
   public void storeCar( Car car );

   public Car findCar( Car car );
}

在CarInventoryTimerEar:

@Stateless
public class CarInventoryTimer {

   @EJB
   private CarDaoRemote _carDaoRemote;

   // do some stuff with _carDaoRemote...

}

所以问题是,如果我用CarInventoryTimerEar打包实体&dao bean,那么app服务器会抱怨我试图再次部署实体-我理解这一点。但是,如果我没有包含得到ClassNotFoundException的类,这也是有意义的。
