Struts2开发包需要:
struts2-core-2.0.9.jar,xwork-2.0.4.jar
ognl-2.6.11.jar,freemarker-2.3.8.jar
commons-logging-api-1.1.jar
在WEB-INF/classes/struts.xml设置do为后缀扩展名
<?xml version="1.0" encoding="UTF-8" ?>

======配置WEB-INF/web.xml====
<?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"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

=====demo.xml====
(放到classes下与struts.xml同一目录)
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="demo" namespace="/" extends="struts-default">
<action name="login" class="txdnet.demo">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>
最后大家注意namespace的作用 比如当namespace="/"时表单中from="login.do"和from="/txdnet/login.do"有什么不同?
如果namespace="/txdnet" 呢?
txdnet的目录必须有么?
success.jsp index.jsp error.jsp文件的目录位置又会产生什么作用呢?
