初次整合struts2和string，在用ant部署时遇到下面的问题
services-undeploy-absolute:
[undeploy] OK - Undeployed application at context path /ch23
[deploy] FAIL - Deployed application at context path /ch23 but context failed to startBUILD FAILED
E:\Workspace\ch23\build.xml:39: FAIL - Deployed application at context path /ch23 but context failed to start
网上查了一些资料，觉得是web.xml的问题
web.xml代码<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

去掉，ant部署成功，但是这个时候主页的login.jsp打不开
报错如下

看意思好像是少了filter，但是加上上面的filter以后ant又报错，甚是不解
