struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" namespace="/" extends="struts-default">
<action name="loginPro" class="org.struts.action.RegistAction">
<result >/WEB-INF/content/welcome.jsp</result>
<result name="error">/WEB-INF/content/error.jsp</result>
</action>
<action name="listuser" class="org.struts.action.listuseraction">

<!-- Add packages here -->
</struts> struts2
[解决办法]
开发工具eclipse：
1 . 新建web项目，在webcontent/web-inf/lib 目录下导入struts2jar包
2 . 在src下新建一个struts.xml文件
3 . 配置web.xml 加入如下：
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
4. 新建三个页面首页，成功页面
index.jsp
<html>
<body>
<form action="" method="execute">
<input name="useranme" type="text">
<input name="password" type="password">
<input type="submit" value="提交">
</form>
</body>
</html>
success.jsp
<html><body>注册成功</body></html>
5. 写action
public void RegisterAction extends ActionSupport｛
private Strring username;
private String password;
public void setUsername(String username){this.username = useranme;}
public String getUsername() {return username;}
//..省略password set get
public void execute(){
//向数据库啊插入数据，或者模拟一个即可
return SUCCESS;
}
｝
5. 配置struts.xml
<package name="abc" extends="struts-default">
<action name="register" class="RegisterAction">
<result name="success">/success.jsp</result>
<result name="input">/index.jsp</result>
</action>
</package>

[解决办法]
贴下报错信息
[解决办法]
Logindata 把这个类贴出来亲。。，对了，你后建类的话，注意首字母大写规范一下。
[解决办法]
你这代码这么乱，怎么看啊，最少你也要说下报什么错
