解决方案 »

  1.   

    An error occurred at line: 140 in the jsp file: /docManage/docuser/addDocUser.jsp
    DocRolePowerDao cannot be resolved to a type140行的 DocRolePowerDao 没引用进来
      

  2.   

    DocRolePowerDao 是不是接口呀，接口不能new
      

  3.   

    DocRolePowerDao是一个类package com.docrolepower.dao;import java.sql.Connection;
    import java.sql.ResultSet;
    import java.sql.SQLException;

    }
      

  4.   

    DocRolePowerDao cannot be resolved to a type
    <%@ page import="com.docrolepower.dao.*" %>
    但是不是已经import了吗？为什么不行，其他地方就是这么用的，这个项目只是从另一台电脑中导出来的，以前电脑上就没问题。
      

  5.   


    DocRolePowerDao是一个类，不是接口
