		SessionFactory sf = (new AnnotationConfiguration().configure("/CFG/hibernate.cfg.xml")).buildSessionFactory();
		
		Session sessao = sf.openSession();
		
		Transaction tx = null;
		
		try {
			tx = sessao.beginTransaction();
			
			Cadastro cad = new Cadastro();
			
			cad.setNome("Jeison Pereira");
			cad.setIdade(28);
			cad.setEmail("jsnpereira@gmail.com");
			
			
			sessao.save(cad);
			
			tx.commit();
		} catch (HibernateException e) {
			tx.rollback();
			e.printStackTrace();
		} finally{
			sessao.close();
		}
}

You need Cadastro.hbm.xml?

[foo123]

the class needs to be inside package folder Persistencia.
since u use annotations i think hbm.xml is not necessary. as i understand it the class is not in the right package/folder

and you should add package Persistencia at the beginning of your class. i think this is the problem

Also does your project use persistence.xml? If so, ensure your class is included in there.
