Meu CustomProvider:

public class CustomProvider extends SpringProvider {

	@Override
	protected void registerCustomComponents(ComponentRegistry registry) {
		//Usage is: register.register(TypeToRegister.class, ImplementationForThisType.class);
		//In this case the implementation is equal to type to register.
		registry.register(SessionCreator.class, SessionCreator.class);
		registry.register(SessionFactoryCreator.class, SessionFactoryCreator.class);

		registry.register(HibernateTransactionInterceptor.class, HibernateTransactionInterceptor.class);
	}

}

Meu web.xml

	<context-param>  
    	<param-name>br.com.caelum.vraptor.provider</param-name>  
   		<param-value>br.com.caelum.vraptor.util.hibernate.HibernateCustomProvider</param-value>  
	</context-param>

Alguém pode me ajudar?
