jsp网页如何实现链接100分相送（在线等）！！！！！！！！！

<a href="a.jsp">my link </a>

解决方案 »

  1.   

    不是啦，，，
    如果是这样就好了，，光键是，，如何在TOMCAT中配置，，
    我把两个文件都拷到同一个ROOT文件目录下，，为什么第一个页面可以看，链接第二个页面就不可以看了，，一片白

    //第一个文件
    <%@ page contentType="text/html;charset=gB2312"%>
    <%@ page import="java.sql.*"%>
    <!--%@ page import="java.sql.Statement"%-->

    <p>添加新的数据库

    第二个文件是叫 Ex1513.jsp 吗？

    你的捕获异常的输出都是空的。这样写错了还不知道！
    估计第二个叶面可能有异常！
