org.hibernate.type.SerializableType - could not read column value from result set

[Gil Carvalho]

Hi

I have another issue with my code.
If i want to delete a many to one record i have this error

INFO : org.hibernate.type.SerializableType - could not read column value from result set: HORA2_33_0_; could not deserialize

HORA2_33_0 is a hibernate name, the real name is HORA_DATA from table and belongs to Reserva class.

@Entity
@Table(name = "RESERVA", schema = "GESTAOTAXI")
public class Reserva implements Serializable {

    private static final long serialVersionUID = 1L;
    private int codReserva;
    private Morada moradaByCodMoradaDe;
    private EmpregadoVeiculo empregadoVeiculo;
    private Morada moradaByCodMoradaPara;
    private Empregado empregado;
    private int estado;
    private Timestamp horaData;

    public Reserva() {
    }

    @Id
    @Column(name = "COD_RESERVA", unique = true, nullable = false, precision = 22, scale = 0)
    @GeneratedValue(strategy = GenerationType.AUTO)
    public int getCodReserva() {
        return this.codReserva;
    }

    public void setCodReserva(int codReserva) {
        this.codReserva = codReserva;
    }

    @ManyToOne(cascade = {CascadeType.REMOVE}, fetch = FetchType.EAGER)
    @JoinColumn(name = "COD_MORADA_DE")
    public Morada getMoradaByCodMoradaDe() {
        return this.moradaByCodMoradaDe;
    }

    public void setMoradaByCodMoradaDe(Morada moradaByCodMoradaDe) {
        this.moradaByCodMoradaDe = moradaByCodMoradaDe;
    }

    @ManyToOne(cascade = {CascadeType.REMOVE}, fetch = FetchType.EAGER)
    @JoinColumn(name = "COD_EMPREGADO_VEICULO")
    public EmpregadoVeiculo getEmpregadoVeiculo() {
        return this.empregadoVeiculo;
    }

    public void setEmpregadoVeiculo(EmpregadoVeiculo empregadoVeiculo) {
        this.empregadoVeiculo = empregadoVeiculo;
    }

    @ManyToOne(cascade = {CascadeType.REMOVE}, fetch = FetchType.EAGER)
    @JoinColumn(name = "COD_MORADA_PARA")
    public Morada getMoradaByCodMoradaPara() {
        return this.moradaByCodMoradaPara;
    }

    public void setMoradaByCodMoradaPara(Morada moradaByCodMoradaPara) {
        this.moradaByCodMoradaPara = moradaByCodMoradaPara;
    }

    @ManyToOne(cascade = {CascadeType.REMOVE}, fetch = FetchType.EAGER)
    @JoinColumn(name = "COD_EMPREGADO")
    public Empregado getEmpregado() {
        return this.empregado;
    }

    public void setEmpregado(Empregado empregado) {
        this.empregado = empregado;
    }

    @Column(name = "ESTADO")
    public int getEstado() {
        return this.estado;
    }

    public void setEstado(int estado) {
        this.estado = estado;
    }

    @Column(name = "HORA_DATA", precision = 6 )
    public Timestamp getHoraData() {
        return this.horaData;
    }

    public void setHoraData(Timestamp horaData) {
        this.horaData = horaData;
    }
}

The error is when this function is called

 @Override
    public void delete(int resId) {
        Reserva ser = (Reserva) session.getCurrentSession().get(Reserva.class, resId);
        session.getCurrentSession().delete(ser);
    }

This the staketrace
