EclipseLink JPA multitenancy

Question

I am using EclipseLink to auto populate the column on inserts. (column i want it to auto update is COMPANY_ID)
Table is like
COMPANY_ID
EMPLOYEE_ID
NAME
SALARY
AGE
My entity is
@Entity
@NamedQueries({
@NamedQuery(name = "EmployeeVpd1.findAll", query = "select o from EmployeeVpd1 o")
@Table(name = "EMPLOYEE_VPD_1")
@Multitenant
@TenantDiscriminatorColumn(name ="COMPANY_ID")
public class EmployeeVpd1 implements Serializable {
private Long age;
@Id
@Column(name="EMPLOYEE_ID", nullable = false)
private Long employeeId;
@Column(length = 30)
private String name;
private Long salary;
public EmployeeVpd1() {
public EmployeeVpd1(Long age, Long employeeId,
String name, Long salary) {
this.age = age;
this.employeeId = employeeId;
this.name = name;
this.salary = salary;
public Long getAge() {
return age;
public void setAge(Long age) {
this.age = age;
public Long getEmployeeId() {
return employeeId;
public void setEmployeeId(Long employeeId) {
this.employeeId = employeeId;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
public Long getSalary() {
return salary;
public void setSalary(Long salary) {
this.salary = salary;
Persistent class is (hard coded that tenant id to Oracle)
<persistence-unit name="EJB">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>java:/app/jdbc/jdbc/VPDDS</jta-data-source>
<class>ejb.EmployeeVpd1</class>
<properties>
<property name="eclipselink.target-server" value="WebLogic_10"/>
<property name="javax.persistence.jtaDataSource"
value="java:/app/jdbc/jdbc/VPDDS"/>
<property name="eclipselink.jdbc.exclusive-connection.mode" value="Always" />
<property name="eclipselink.tenant-id" value="Oracle"/>
</properties>
</persistence-unit>
Java class for creating the entity and inserting it to db
@PersistenceUnit
EntityManagerFactory emf = Persistence.createEntityManagerFactory("EJB");
em=emf.createEntityManager();
em.persist(employee1)
Its inserting the row into the table but the COMPANY_ID is not getting set to Oracle . Its always setting to null

Hi,
The multitenancy feature wasn't implemented till 2.3. Can you try a more recent version?
