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!
Paolo.

my_userbean.getId()

my_userbean.getId() doesn't work...i get a null value... :(

I found the solution!!!
In my session bean i wrote:


public void save(UserEBean bean)
{
// TODO Auto-generated method stub
manager.persist(bean);
}


...but the method must be return an "UserBEan" object...the returned object must be the object that i passed to save() method....


public UserEBean save(UserEBean bean)
{

manager.persist(bean);

return bean;

}
