How to map a class attribute using hibernate?
<p>When I try to map the Phone on a Phone in the Contact class it gives the following error: </p>

<blockquote>
  <p>Initial creation of the SessionFactory object failed. Error: org.hibernate.MappingException: Could not determine type for: com.livro.capitulo3.crudannotations.Telephone, at table: contact, for columns: [org.hibernate.mapping.Column (numPhone)]
  Error closing insert operation. Message: null
  java.lang.ExceptionInInitializerError
  The mapping class is as follows:</p>
</blockquote>

<p>//Class Contato</p>

<pre><code>package com.livro.capitulo3.crudannotations;

import java.sql.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Table;

import org.hibernate.annotations.ManyToAny;

@Entity
@Table(name = "contato")
public class ContatoAnnotations {

    @Id
    @GeneratedValue
    @Column(name = "codigo")
    private Integer codigo;

    @Column(name = "nome", length = 50, nullable = true)
    private String  nome;

    @Column(name = "telefone", length = 50, nullable = true)
    private String  telefone;

    @Column(name = "email", length = 50, nullable = true)
    private String  email;

    @Column(name = "dt_cad", nullable = true)
    private Date        dataCadastro;

    @Column(name = "obs", nullable = true)
    private String  observacao;


    //Como ficaria a annotation aqui???? Só vou persistir esta tabela
    @OneToMany
    private Telefone numTelefone;
    ...
    //Getters e Setters

}

<p>//Class Telefone:</p>

    public String getNumero() {
        return numero;
    }

    public void setNumero(String numero) {
        this.numero = numero;
