It's not better.

Try this from the Hibernate annotiations guide:
To map a bidirectional one to many, with the one-to-many side as the
owning side, you have to remove the mappedBy element and set the many
to one @JoinColumn as insertable and updatable to false. This solution
is obviously not optimized and will produce some additional UPDATE
statements.
See section 2.2.5.3.2.1. here: http://tinyurl.com/ypdln3

I think it's correct :
---------------------------------
@Entity
public class Enquete implements java.io.Serializable {
...
@OneToMany(mappedBy="enquete",cascade=CascadeType.ALL)
public Set<Modele> getModeles() {
return modeles;
}
...
}
@Entity
public class Modele implements java.io.Serializable {
...
@ManyToOne
@JoinColumn(name="ENQUETE_ID")
public Enquete getEnquete() {
return enquete;
