Question

I have a Method annotated with @RolesAllowed, this method needs to be invoked from an timer (@Schedule), that is located in an other Ejb. But I only get a Authorization Exception: WARNUNG: javax.ejb.AccessLocalException: Client not authorized for this invocation

 @RolesAllowed("user")
 @Stateless
 public class RatingService {
    public void recalculateRating() {...}
 }

 @Singleton
 @Startup     
 public class TimerService {

     @EJB private RatingService ratingService;

     @Schedule(minute = "0", hour = "*")
     public void timerTriggeredRecalculate() {        
          this.ratingService.recalculateRating();
     }
 }

I accept this exception, but how to invoke a @RolesAllowed protected method from a Timer?

I also tryed to add @RunAs("user") to the TimerService Class. But then I get this exception:

The Server is a Glassfish 3.1.2

Answer 1

You’ll need to use an EJB that is annotated @RunAs. If the timer method is the only method exposed by the TimerService EJB, then you could add the @RunAs to that class directly. Otherwise, you’ll need to create an intermediate PrivilegedRatingService EJB that has the @RunAs.

(As an aside TimerService is probably a poor choice for an EJB class name given the conflict with javax.ejb.TimerService.)
