How to display objects from a list?

Question

I have the Personal class which has the following method:

public List<Pessoa> BuscarTodos() {

    List<Pessoa> list = null;

    EntityManager em = getEM();

    try {

        list = em.createQuery("select t from Pessoa t").getResultList();

    } catch (HibernateException e) {
        System.out.println(e.toString());

    } finally {
        em.close();
    }

    return list;

}

And in my Servlet, I have the following doGet:

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

    PessoaDAO<Pessoa> db = new PessoaDAO<Pessoa>();

    try {

    List<Pessoa> list = db.BuscarTodos();
    req.setAttribute("list", list);

    getServletContext().getRequestDispatcher("/index.jsp").forward(req, resp);

    System.out.println(req.getAttribute("list"));

    } catch (Exception e) {

        e.printStackTrace();
    }


}

'Cause when I give a sysout, it shows up like this:

[model. Person@7d5d4b78, model.Person@1eb15301, model.Person@15f8c5af]

And not the list itself?

If it helps, this is class person:

@Entity 
public class Pessoa {

    @Id
    @GeneratedValue
    @Column(name="ID")
    private int id;

    @Column(name="NOME")
    private String nome;

    @Column(name="CPF")
    private String cpf;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getCpf() {
        return cpf;
    }

    public void setCpf(String cpf) {
        this.cpf = cpf;
    }


}

When you do this SELECT by Hibernate, it creates a row object from your database. These values that appear are the address that this object is allocated to in your memory. When you have the object printed, it printed the address and not the data of that object. You can override the toString() method to print the data however you want.
