Secondary table

[rani vini]

How can map these two tables using secondary table
Table EMP
ID NUMBER primarykey, EMPNAME VARCHAR2(15)
Table DEPT
EMPID NUMBER , DEPTNAME VARCHAR2(15)

Where EMPID refers to the ID column of EMP

My mapping calss is like below
@Entity
@Table(name="emp")
@SecondaryTable(name="dept")
@PrimaryKeyJoinColumn( name = "EMPID", referencedColumnName = "ID")
public class Employee {
@Id
@GeneratedValue(strategy=GenerationType.AUTO, generator="EMP")
@SequenceGenerator(name="EMP", sequenceName="SEQ_EMP")
long Id;


@Column(name="EMPNAME")
String empName;

@Column(table="dept")
String deptName;

When I try to persist like below

Employee empObj = new Employee();
empObj.setEmpName("emp1");
empObj.setDeptName("dept1");
em.persist(empObj);

It is displayign the Sql statements like
Hibernate: insert into emp (EMPNAME, Id) values (?, ?)
Hibernate: insert into dept (deptName, Id) values (?, ?)
In DEPT table there is no "ID" column. So Iam getting error.
The insert Statement for DEPT should contain "DEPTNAME and EMPID" instead of "DEPTNAME AND ID"

Can anyone help?

Could it be the referencedColumnName = "ID" element?
