Olá,

duvida como faço pra acessar o arquivo xml

SessionFactory sf = new Configuration().configure("br/com/dao/hibernate.cfg.xml").buildSessionFactory();
		Session s = sf.openSession();

pra ler a configuração do banco
pois está me dando o erro abaixo e estou usando anotação na tabela.

se alguém puder me ajudar …

agradeceria.

- Configuration resource: br/com/dao/hibernate.cfg.xml
Erro na rotina getUsuarios() =org.hibernate.MappingException: An AnnotationConfiguration instance is required to use &lt;mapping class="br.com.marisanova.model.PubUsuario"/&gt;

public List listarUsuario(){
		System.out.println("listarUsuario()");
		SessionFactory sf = new Configuration().configure("br/com/dao/hibernate.cfg.xml").buildSessionFactory();
		Session s = sf.openSession();
		s.beginTransaction();
        List lista = s.createQuery("from Usuario").list();
        s.getTransaction().commit();
        return lista;
	}

&lt;session-factory&gt;

		&lt;property name="hibernate.dialect"&gt;org.hibernate.dialect.Oracle9iDialect&lt;/property&gt;
		&lt;property name="hibernate.connection.driver_class"&gt;oracle.jdbc.driver.OracleDriver&lt;/property&gt;
		
		&lt;property name="hibernate.connection.url"&gt;jdbc:oracle:thin:@129.1.30.999:1521:DES&lt;/property&gt;
		&lt;property name="hibernate.connection.username"&gt;des&lt;/property&gt;
		&lt;property name="hibernate.connection.password"&gt;des&lt;/property&gt;

		&lt;property name="hibernate.show_sql"&gt;true&lt;/property&gt;
		&lt;property name="hibernate.format_sql"&gt;true&lt;/property&gt;

		&lt;property name="hibernate.c3p0.min_size"&gt;5&lt;/property&gt;
		&lt;property name="hibernate.c3p0.max_size"&gt;20&lt;/property&gt;
		&lt;property name="hibernate.c3p0.timeout"&gt;180&lt;/property&gt;
		&lt;property name="hibernate.c3p0.idle_test_period"&gt;100&lt;/property&gt;

		
		&lt;mapping class="br.com.marisanova.model.Usuario"/&gt;

o que fiz pra funcionar …

package br.com.marisanova.dao;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {

	private static SessionFactory sessionFactory; 
	
	static { 
		try { 
//			Create the SessionFactory from hibernate.cfg.xml 
			sessionFactory = new AnnotationConfiguration() 
			.configure("br/com/marisanova/dao/hibernate.cfg.xml") 
			.buildSessionFactory(); 
		} catch (Throwable ex) { 
//			Make sure you log the exception, as it might be swallowed 
			System.err.println("Initial SessionFactory creation failed." + ex); 
			throw new ExceptionInInitializerError(ex); 
		} 
	} 
	
	public static SessionFactory getSessionFactory() { 
		if(sessionFactory == null){ 
			try { 
				sessionFactory = new AnnotationConfiguration() 
				.configure("br/com/marisanova/dao/hibernate.cfg.xml") 
				.buildSessionFactory(); 
			} catch (Throwable ex) { 
 
				System.err.println("Initial SessionFactory creation failed." + ex); 
				throw new ExceptionInInitializerError(ex); 
			} 
			
		} 
		return sessionFactory; 
	} 
	
}
