EJB3- get id after persist

Question

Hi to all...i have an entity bean (UserEBean) and its "Id" is defined like:
@Id(generate=GeneratorType.SEQUENCE, generator="USERS_SEQ")
@javax.persistence.SequenceGenerator(
          name="USERS_SEQ",
          sequenceName="users_user_id_seq"
@Column(name="user_id", nullable=false)     
     public Long getUserId() {
          return userId;
Respective session bean has the method:
public void save(UserEBean bean)
          // TODO Auto-generated method stub
          manager.persist(bean);          
In an other class i set properties in an UserEBean variable and then i call:
userDAO.save(my_userbean);
How can i get the entity's ID which i just persisted?
Thanks to all!
