摘要: (我的分快没了)大家帮忙看看吧，我捣鼓一天了，筋疲力尽！！！为什么这个Struts始终徘徊在表单验证这里，不再往下走了，似乎Action的exce

就是用户填写完姓名、密码、标题、内容后，点击提交按钮应该到达success这个页面，但是，我始终实现不了，始终徘徊在表单验证这里，不往下走了，似乎根本就没有调用Action的excecute（）方法；
我到现在也没找到是哪里的错误，人多力量大，大家都帮忙看看是哪里的错误吧，我鼓捣一天了，筋疲力尽。。。。
我把代码贴上来：
send.jsp:

<%@ page language="java" import="java.sql.*" pageEncoding="UTF-8" contentType="text/html; charset=UTF-8" errorPage="" %>

这个类里面不该有业务逻辑, 连接也不要放在这里, actionForm类只是收集jsp页面的数据的!

为什么没有执行你所执行的任务, 应该是你的配置有问题, 自己多调试一下吧

提交的时候有没有什么错误提示？
