解决方案 »

  1.   

    注：at com.iarown.user.dao.GetData.getUser(GetData.java:33)    为行  Session session = HibernateUtility.openTheHibernateSession();
      

  2.   

    没有人知道怎么回事 吗 ？请教高手帮帮忙。我不知道Session的取得那里出错了，就是使用Hibernate自己生成的Session工厂也出这样的错误。
      

  3.   


    java.lang.ClassNotFoundException: net.sf.cglib.proxy.CallbackFilter少了包吧
    去下一个cglib2.0,或者其他版本,呵呵
    不是不想来回答,是没有时间来看,现在下班,来下,呵呵
    希望谅解.
      

  4.   

    还有,如果楼主是关于Hibernate,一步一步的运行下去,缺少包,给他添加上,如果是session,需要添加上一个Transaction,当然就是它的可行性过程而已,
    解决了就好了,哈哈
