Where to place @SqlResultSetMapping in case of @ConstructorResult

Question

I\'m trying to map a non-entity pojo with the createNativeQuery method of entityManager of jpa. By using something like this

@SqlResultSetMapping(name=\"ResultMa         


        

Answer 1

Where I am supposed to put SqlResultSetMapping so that the entityManager will able to recognize it?

As far as I can see it varies from a persistence provider:

• EclipseLink: put it at any class in the classpath

• Hibernate: put it at any class annotated with @Entity; in fact I am able to reproduce the error when I put it elsewhere:

  org.hibernate.MappingException: Unknown SqlResultSetMapping [ResultMapping]
  

Tested with EclipseLink 2.5.2, Hibernate 4.3.8.Final

In general to make your application portable across JPA providers it would be the best to put SqlResultSetMapping at any entity class.
