私は方法を行いますpatientCardMB.delete()：
public String delete() {
System.out.println(patientCard);
try {
patientCardDao.delete(patientCard);
} catch (EJBException e) {
sendErrorMessageToUser("Błąd usuwania wpisu");
}
sendInfoMessageToUser("Wpis usunięty");
return "delete";
}
PatientCardDAo.delete:
@Override
public void delete(PatientCard patientCard) {
PatientCard toRemoved = em.merge(patientCard);
em.remove(toRemoved);
}
エンティティの患者カード:
public class PatientCard implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
private Integer id;
@Basic(optional = false)
@NotNull
@Column(name = "dateVisit")
@Temporal(TemporalType.TIMESTAMP)
private Date dateVisit;
@Size(max = 4000)
@Column(name = "diagnosis")
private String diagnosis;
@Size(max = 250)
@Column(name = "medications")
private String medications;
@JoinColumn(name = "patient_id", referencedColumnName = "id")
@ManyToOne(optional = false)
private User patientId;
@JoinColumn(name = "doctor_id", referencedColumnName = "id")
@ManyToOne(optional = false)
private User doctorId;
削除しようとすると、次のエラーが発生します。

なぜこのエラーが発生するのかわかりません。以前に同様のエンティティを削除しましたが、すべて機能しました。
