public class HibernateUtil {
private static SessionFactory factory;
static {
AnnotationConfiguration configuration = new AnnotationConfiguration();
configuration.configure();
factory = configuration.buildSessionFactory();
}
public static Session getSession() {
return factory.openSession();
}
}
Criei uma classe SessionUtil.java dentro da package util com oseguinte codigo:
package util;
import java.util.ResourceBundle;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
public class SessionUtil {
private static ResourceBundle bundle = ResourceBundle.getBundle("Mensagem",
FacesContext.getCurrentInstance().getViewRoot().getLocale());
public static void addErrorMessage(String msg) {
msg = bundle.getString(msg);
FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_ERROR, msg, msg);
FacesContext fc = FacesContext.getCurrentInstance();
fc.addMessage(null, facesMsg);
}
public static void addSucessMessage(String msg) {
msg = bundle.getString(msg);
FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_ERROR, msg, msg);
FacesContext fc = FacesContext.getCurrentInstance();
fc.addMessage("Sucesso", facesMsg);
}
}

this.cd_idioma = cd_idioma;
}
public void setDesc_idioma(String desc_idioma) {
this.desc_idioma = desc_idioma;
}
}

// se ocorrer algo errado cancela a transacao
t.rollback();
SessionUtil.addErrorMessage("Falha na operação");
} finally {
//fecha a sessao com o banco de dados
