  1.   

    hibernat。jar包 放入了吗？
      

  2.   

    javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/hibernate/HibernateException
    java.lang.NoClassDefFoundError: org/hibernate/HibernateException
    java.lang.ClassNotFoundException: org.hibernate.HibernateException
    看看这三句，应该是你的hibernate的jar包没导入。
      

  3.   

    跟你的PACKAGE有关，javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/hibernate/HibernateException显示得问题是类未定义，也有可能是你没有引入相应的包。
    java中的包中通配符*是不能应用到下一级package中的，所以楼主检查你的包是没有问题的，才能正确的找到问题所在。
