Wow!
I tried put "insertable=false, updatable=false" in the fields they are FK and PK, so it worked as magic.
Thank you very much, ldemichiel!!
To the other people who had the same problem as I did, here comes the configuration:
public class [b]ClientCard[/b]{
@Id
@Column(name = "car_id_card")
private int idCard;
@Id
@Column(name = "cli_id_client")
private int idClient;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns({_at_JoinColumn(name = "car_id_card", insertable=false, updatable=false)})
private Card card;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns({_at_JoinColumn(name = "cli_id_client", insertable=false, updatable=false)})
private Client client;
}
