index.jsp可以正常显示，但是点击Test按钮会出现错误：
type Status report
message /struts2qs/Test
description The requested resource (/struts2qs/Test) is not available.
------解决方案--------------------
struts.xml
<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="lee" extends="struts-default">
<action name="Test" class="TestAction">
<result name="success">welcome.jsp </result>
</action>
</package>
</struts>
配置中class需要加上包名的啊
------解决方案--------------------
你的action路径错了
把你那个package的name属性去掉就ok了
action后面加上.action
