I have a simple system of opening / calling query. I am in error when trying to insert a new call.
I started using Hibernate and I have a problem with "persist" to add a call to a certain call queue.
Below the codes and log:
So-called Class
@Entity
public class Chamado {
/**
*
*/
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="ID_CHAMADO")
private int id;
@NotNull
@Column(name="DESCRICAO")
@Size(max=100)
private String descricao;
@NotNull
@Column(name="STATUS")
private String status;
@NotNull
@Column(name="DT_ABERTURA")
private Date dataAbertura;
@Column(name="DT_FECHAMENTO")
private Date dataFechamento;
@NotNull(message="Não pode ser vazio")
@ManyToOne
@JoinColumn(name="ID_FILA")
private Fila fila;
Chamadodao class
public Chamado salvarNovoChamado(Fila fila, Chamado chamado) throws IOException{
manager.persist(chamado);
return chamado;
}
Note: I know I do not use the "queue" parameter for anything, because it is the old model, but I still have doubts about how the Hibernate will pull the ID_FILA to link.

I believe you are passing the object by filling its id, hence the error. It is being created or updated?
– Giuliana Bezerra
@Giulianabezerra then, I have the FILA ID of who will belong to the call, this FILA is another object, I realized that the same FILA ID is going to the CALLED ID also.
– Kennedy Anderson
This is what cannot happen. The id of the called object is generated by Hibernate, depending on how you set up your PK settings. See who adds this information to the object and clear the value.
– Giuliana Bezerra
Only myself I pass the value of the ID, because Hibernate is taking the value of my select that I have in JSP. That is named "id". Which in this case is the same name in both classes, Call and Queue.
– Kennedy Anderson
The object is being updated then, and not created?
– Giuliana Bezerra
Yes, sorry I said wrong earlier. I only assign values to classes and use persist.
– Kennedy Anderson
Let’s go continue this discussion in chat.
– Kennedy Anderson
Oh my problem now is to pass the queue object next to the called object. List of Constraint violations:[ ConstraintViolationImpl{interpolatedMessage='Não pode ser vazio', propertyPath=fila, rootBeanClass=class br.usjt.arqsw.entity.Chamado, messageTemplate='Não pode ser vazio'}
]] with root cause
