//运行时异常在netbeans中调用以下代码时会发生运行时异常。在日食中工作得很好。

    public List<Ticket> findOpenTickets() {
            Session session = null;

            try {
                session = getSession();
                Criteria criteria = session.createCriteria(getReferenceClass());
                            criteria.add(Restrictions.eq(Ticket.PROP_CLOSED, Boolean.FALSE));
                List list = criteria.list();
                return list;
            } finally {
                closeSession(session);
            }
        }

我无法解决此异常。因为一切似乎都很好，相同的代码在eclipse中正常运行但产生运行时异常。

检查你的hibernate.dialect是否正确？它一定是你的DB ..

为什么这个代码在netbeans中抛出ClassCastException，而它在eclipse中正常运行
