Exception Description: An incompatible mapping has been encountered between [class Entidades.Pais] and [class Entidades.Provincia]

Question

This is the class Provincia with their attributes and I want to make a relationship ManyToOne with the class Pais (a Pais has many Provincia)

public class Provincia implements Serializable {
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "idProvincia")
    private Collection<Localidad> localidadCollection;
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "Id")
    private Long id;
    @Basic(optional = false)
    @Column(name = "Nombre")
    private String nombre;
    @NotNull
    @Basic(optional = false)
    @ManyToOne
    @JoinColumn(name="Pais_ID", referencedColumnName = "Pais_ID")
    private Pais idPais;
}

Now the class Pais and their attributes

public class Pais implements Serializable {
    private static final long serialVersionUID = 1L;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "idPais")
    private Collection<Provincia> provinciaCollection;
    @Id
    @Basic(optional = false)
    @Column(name = "Id")
    private Long id;
    @Basic(optional = false)
    @Column(name = "Nombre")
    private String nombre;
}
