SEVERE: Initial SessionFactory creation failed !
私のhtmlは簡単です：
<form action="LuckyNumberServlet" method="POST">
<input type="submit" value="Generate Lucky Number">
</form>
私のJavaメソッドは非常に単純です（LuckyNumberDAOから）：
public void persist_cs_with_cfg(LuckyNumberPojo transientInstance) throws Exception {
log.log(Level.INFO, "Persisting LuckyNumberPojo instance ...");
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
try {
session.beginTransaction();
session.persist(transientInstance);
session.getTransaction().commit();
log.log(Level.INFO, "Persist successful...");
} catch (RuntimeException re) {
session.getTransaction().rollback();
log.log(Level.SEVERE, "Persist failed...", re);
throw re;
}
}
私は何が欠けていますか？
