hello,
I'm confusing about Hibernate behavior and JPA spec.
please tell me below behavior that due to JPA spec or not.
Entity Classes:
Code:
@Entity
public class NewEntity implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Embedded
private NewEntityEE neee = new NewEntityEE();
}
Code:
@Embeddable
public class NewEntityEE implements Serializable {
@OneToOne(cascade = {CascadeType.PERSIST})
@JoinColumn(nullable = false)
private NewEntity3 ne3 = new NewEntity3();
}
Code:
@Entity
public class NewEntity3 implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
}
the Service class:
Code:
@Stateless
public class NewEJB {
@PersistenceContext
private EntityManager em;
public NewEntity create(){
NewEntity ne = new NewEntity();
em.persist(ne);
return ne;
}
}
invoke NewEJB#create(), exception occured:
Code:
WARN: HHH000437: Attempting to save one or more entities that have a non-nullable association with an unsaved transient entity. The unsaved transient entity must be saved in an operation prior to saving these dependent entities.
Unsaved transient entity: ([entity.NewEntity3#<null>])
Dependent entities: ([[entity.NewEntity#<null>]])
Non-nullable association(s): ([entity.NewEntity.ne3])

in addition, when i remove annotation "@JoinColumn(nullable = false)" of NewEntityEE, it worked.
or make relation hierarchy to direct like NewEntity -> NewEntity3
with annotation "@JoinColumn(nullable = false)", it worked.
environment:
- Hibernate 4.1.1
- GlassFish 3.1.2
- Sun JDK 1.7.0_03
thanks.
