Estou implementando um servlet para que possa carregar a SessionFactory do hibernate logo na inicialização do tomcat o que reduz significativamente o tempo do primeiro acesso na minha aplicação pelos usuários, pois bem, criei uma classe HibernateUtil dessa forma:
public class HibernateUtil {
private static Configuration configuration;
private static SessionFactory sessionFactory;
private static final ThreadLocal threadSession = new ThreadLocal();
private static final String ERR_SESSION_FACTORY = "Erro criando a session factory";
static {
try {
configuration = new Configuration().configure();
sessionFactory = configuration.buildSessionFactory();
} catch (HibernateException he) {
SystemLog.error(ERR_SESSION_FACTORY, he);
}
}
...
a aplicação está funcionando “normalmente” porém notei que na inicialização do Tomcat é lançada sempre essa excessão:
java.lang.ClassCastException: br.com.sperto.dao.hibernate.HibernateUtil
