How do I use a managed bean in another managed bean

Question

I have two managed beans. One is backing bean for a form and the other is used to access a database table.
1st bean
public class TestDBAO
@PersistenceContext
private EntityManager em;
public void addEntry(PersonObj person)
em.persist(person);
public class formdata
private String id;
private String fname;
private String lname;
getter functions
setter functions
public String submit()
in here i want to call addEntry function from TestDBAO
How can I achieve this or is there another way to do this?

Answer 1

Do I understand correctly that you have definied TestDBAO as a session scoped managed bean? Why?
You don't need that. Just create and call TestDBAO in the backing bean. Or if you want only one instance of TestDBAO during the session, then create a singleton constructor and eventually make the methods static.
