i need help hibernate mapping one-to-many don´t know why wrong

public class direccion { private long id; private string calle; private int numero; private list<persona> habitantes; public direccion(){ } public direccion(long id, string calle, int numero, list<persona> habitante) { super(); this.id = id; this.calle = calle; this.numero = numero; this.habitantes = habitante; } public long getid() { homecoming id; } public void setid(long id) { this.id = id; } public string getcalle() { homecoming calle; } public void setcalle(string calle) { this.calle = calle; } public int getnumero() { homecoming numero; } public void setnumero(int numero) { this.numero = numero; } public list<persona> gethabitantes() { homecoming habitantes; } public void sethabitantes(list<persona> habitantes) { this.habitantes = habitantes; } @override public string tostring() { homecoming "direccion [id=" + id + ", calle=" + calle + ", numero=" + numero + ", habitantes=" + habitantes + "]"; } }

another class:

public class persona { private long id; private long nombre; public persona(){ } public persona(long id, long nombre) { super(); this.id = id; this.nombre = nombre; } public long getid() { homecoming id; } public void setid(long id) { this.id = id; } public long getnombre() { homecoming nombre; } public void setnombre(long nombre) { this.nombre = nombre; } @override public string tostring() { homecoming "persona [id=" + id + ", nombre=" + nombre + "]"; } }

the mapping

<?xml version="1.0" encoding="utf-8"?> <!doctype hibernate-mapping public "-//hibernate/hibernate mapping dtd 3.0//en" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="datos.direccion" table="direccion"> <id column="id" name="id"> <generator class="identity"> </generator> </id> <property column="calle" name="calle" type="string" /> <property name="numero" column="numero" type="int" /> <set name="habitantes" table="persona" inverse="true" lazy="true" fetch="select"> <key> <column name="idpersona" not-null="true" /> </key> <one-to-many class="datos.persona" /> </class> </hibernate-mapping>

another mapping:

<?xml version="1.0" encoding="utf-8"?> <!doctype hibernate-mapping public "-//hibernate/hibernate mapping dtd 3.0//en" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="datos.persona" table="persona"> <id column="id" name="id"> <generator class="identity"/> </id> <property column="nombre" name="nombre" type="string" /> <many-to-one name="direccion" class="datos.direccion" column="idpersona" not-null="true"/> </set> </class> </hibernate-mapping>

hibernate configuration
