У меня есть сущность с именем Medico , которая была создана как класс сущности из базы данных, поэтому я думаю, что определение сущности здесь является отказоустойчивым, тем не менее, определение следующее:
@Entity
@Table(name = "medico")
@XmlRootElement
@NamedQueries({All named queries here})
public class Medico implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@NotNull
@Column(name = "idMedico")
private Integer idMedico;
@Basic(optional = false)
@NotNull
@Column(name = "Identificacion")
private int identificacion;
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 33)
@Column(name = "Primer_Nombre")
private String primerNombre;
@Size(max = 33)
@Column(name = "Segundo_Nombre")
private String segundoNombre;
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 33)
@Column(name = "Primer_Apellido")
private String primerApellido;
@Size(max = 33)
@Column(name = "Segundo_Apellido")
private String segundoApellido;
@Basic(optional = false)
@NotNull
@Column(name = "Telefono")
private long telefono;
@Column(name = "Telefono_Celular")
private BigInteger telefonoCelular;
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 33)
@Column(name = "Direccion")
private String direccion;
// Constructors..
// Getters and setters..
}
Я хочу создать новые Medico сущности в базе данных MySql, и вот как я это делаю:
@ManagedBean
@ViewScoped
public class ConsultaMedicos implements Serializable {
// Variables Definition ..
@EJB
private DoctorsFacadeLocal doctorsFacade;
// Constructor and other methods ..
public String save()
{
try{
doctorsFacade.save(consultedDoctor);
FacesMessage fm = new FacesMessage(FacesMessage.SEVERITY_INFO, CREATE_SUMMARY, null);
FacesContext.getCurrentInstance().addMessage(CREATE_SUMMARY, fm);
}
catch(Exception ex){
FacesMessage fm = new FacesMessage(FacesMessage.SEVERITY_ERROR, CREATE_ERROR_SUMMARY, null);
FacesContext.getCurrentInstance().addMessage(CREATE_ERROR_SUMMARY, fm);
return null;
}
return "listaMedicos.xhtml";
}
...
}
@Local
public interface DoctorsFacadeLocal {
List<Medico> findAllDoctors();
Medico findDoctorByIdNumber(int identificacion);
void edit(Medico medico);
void save(Medico medico);
}
@Stateless
public class DoctorsFacade implements DoctorsFacadeLocal {
@PersistenceContext
private EntityManager em;
// Other methods..
@Override
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void save(Medico medico)
{
em.persist(medico);
em.flush();
}
}
После того, как я позвонил save()
со своей страницы JSF, я получил следующее исключение:

Что я делаю не так?Чего мне не хватает?
Если это служит чему-то, то вот моя настойчивость. Xml
