          Yes.

          "Cannot create TypedQuery for query with more than one return using requested result type [edu.unl.sbe.model.servicios.Becario]"

          Since you're not selecting a complete record but individual fields, aggregated and calculated values you cannot return them as List of Entities.

          The result of the query will be a list of Object[].
