Session problem in LazyFetch

Question

Hi all,
I have two entities: User and InfoUser in my website.
User has much "InfoUser".
@OneToMany(cascade = CascadeType.ALL, mappedBy = "user")
private List<InfoUser> infos = new LinkedList();
// Code..
public List<InfoUser> getInfos(){
      return infos;
}When I use the userFacade.findAll(), it return all the users in a List. All ok.
When I call the getInfos() from a User I receive an error message:
org.apache.jasper.JasperException: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: org.ianaz.bean.User.InfoUser, no session or session was closedI won't use EAGER type for performance.
Anyone has a solution?
Thanks in advance

Ok.
I have Categoria. It has more Documento
    @OneToMany(mappedBy="categoria", cascade=CascadeType.ALL)
    private List<Documento> documenti = new LinkedList();Then I have a Stateless class named CategoriaFacade
It has some metods
    @PersistenceContext
    private EntityManager em;
    public void create(Categoria categoria) {
        em.persist(categoria);
    public List findAll() {
        return em.createQuery("select object(o) from Categoria as o").getResultList();
...I will call the findAll() method from a JSP page.
If I call from a Servlet it's easy with the code:
public class NewServlet extends HttpServlet {
    @EJB
    private CategoriaFacadeLocal categoriaFacade;
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        categoriaFacade.METHOD_FROM_CATEGORIAFACADECLASS();
}But I don't know how to call methods from a jsp... Understand? :-)
Thanks in advance
