Java ee interface conditional inject

I have the following interface:

public interface ResultEvaluationInterface {
    public void evaluateResults(Event e);
}

and now i want to inject in my class depending on my Event.type different classes with the same implementation. Something like that:

@Stateless
@LocalBean    
public class ResultEvaluation implements ResultEvaluationInterface {

    @Override
    public void evaluateResults(Event e) {
        switch (e.getType()) {
            case Type.Production:
               // inject and call ResultEvaluationProductionEJB.evaluateResults(e)
            case Type.Development:
               // inject and call ResultEvaluationDevelopmentEJB.evaluateResults(e)
            default:
               throw new UnsupportedOperationException("Not supported yet.");
        }
    }

}

ResultEvaluationProductionEJB and ResultEvaluationDevelopmentEJB both implement the interface. Anybody an idea how to do that in a good way?
