Hibernate Persist error

1

I have a simple system for opening / querying calls. I'm having trouble typing a new call.

I started using Hibernate and I have a problem with "persist" to add a call to a certain queue of calls.

Below the codes and log:

Calling 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;

ADO Call Class

public Chamado salvarNovoChamado(Fila fila, Chamado chamado) throws IOException{
        manager.persist(chamado);
        return chamado;
    }

Note: I do not use the "queue" parameter for anything, since it is from the old template, but I still have questions about how Hibernate will pull ID_FILA to link.

Problem: Attribute "queue" that is an object, was being passed as null.

Solution: Changed select name in JSP from "queue" to "queue.id"
