Here is the Base Class
| public class BaseDeptDTOImpl implements Serializable {
|
| private static final Log log = LogFactory.getLog(BaseDeptDTO.class);
|
|
| /** Primary key. */
| private int deptId;
|
| /**
| * auto_increment
| *
| * Get the primary key.
| *
| * @return The primary key.
| */
| @javax.persistence.Id
@javax.persistence.GeneratedValue(strategy=javax.persistence.GenerationType.AUTO)
| @javax.persistence.Column(name = "dept_id")
| public int getDeptId() {
| return deptId;
| }
|
| /**
| * auto_increment
| *
| * Set the primary key.
| *
| * @param deptId The primary key.
| */
| public void setDeptId(int deptId) {
| this.deptId = deptId;
| }
|
| /** Regular field. */
| private java.lang.String deptName;
|
| /**
| * Get the deptName.
| *
| * @return The deptName.
| */
| @javax.persistence.Column(name = "dept_name")
| public java.lang.String getDeptName() {
| return deptName;
| }
|
| /**
| * Set the deptName.
| *
| * @param deptName The deptName.
| */
| public void setDeptName(java.lang.String deptName) {
| this.deptName = deptName;
| }
|
| /** Association. */
| private
java.util.Collection<tv.probability.referenceimplementation.dto.EmpDTO> emps;
| /**
| * Get the emps.
| *
| * @return The emps.
| */
| @javax.persistence.OneToMany(cascade =
javax.persistence.CascadeType.ALL, fetch = javax.persistence.FetchType.EAGER)
| @javax.persistence.JoinColumn(name = "dept_id")
| public
java.util.Collection<tv.probability.referenceimplementation.dto.EmpDTO>
getEmps() {
| return emps;
| }
| /**
| * Set the emps.
| *
| * @param emps The emps.
| */
| public void
setEmps(java.util.Collection<tv.probability.referenceimplementation.dto.EmpDTO>
emps) {
| this.emps = emps;
| }
| }
|
and here is the extending class
| @javax.persistence.Entity
| @org.hibernate.annotations.Entity(dynamicInsert = true)
| @javax.persistence.Table(name = "dept")
| public class DeptDTOImpl extends BaseDeptDTOImpl implements DeptDTO {
| private static final Log log = LogFactory.getLog(DeptDTOImpl.class);
|
| /** Primary key. */
| private int deptId;
|
| /**
| * auto_increment
| *
| * Get the primary key.
| *
| * @return The primary key.
| */
| @javax.persistence.Id
@javax.persistence.GeneratedValue(strategy=javax.persistence.GenerationType.AUTO)
| @javax.persistence.Column(name = "dept_id")
| public int getDeptId() {
| return deptId;
| }
|
| /**
| * auto_increment
| *
| * Set the primary key.
| *
| * @param deptId The primary key.
| */
| public void setDeptId(int deptId) {
| this.deptId = deptId;
| }
| }
|
This compiles and runs, but the inherited deptName is not persisted to the
database, it is ommited from the SQL entirely.
If I add the entity annotations to the Base class:
| @javax.persistence.Entity
| @org.hibernate.annotations.Entity(dynamicInsert = true)
| @javax.persistence.Table(name = "dept")
|
I get the exception:
| FATAL 05-02 09:00:24,776
(PersistenceXmlLoader.java:parsePersistenceUnit:101) -refImplDB JTA
| ERROR 05-02 09:00:28,605 (AbstractController.java:incrementState:350)

| org.hibernate.AnnotationException: Unable to define/override @Id(s) on a

|
btw. I am running this using EMbeddable EJBs and JUnit.
