Olá galera.
Estou aprendendo hibernate,porém estou com um problema ao abrir uma session,já procurei erros parecidos no guj,mas não encontrei uma solução que resolvesse meu problema…

Segue o Erro : 

WARN: HHH000223: Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/. Use namespace http://www.hibernate.org/dtd/ instead. Refer to Hibernate 3.6 Migration Guide!
org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml

	at Entidades.Teste.main(Teste.java:8)

Segue o Código da cfg.xml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
		"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
		"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.password">root</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost/jbsdb</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        
        <mapping-resource="Cliente.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

Espero que possam me ajudar,desde já agradeço.

        <mapping resource="Cliente.hbm.xml"/>
