使用struts2标签需要配置嘛?为什么我的页面上的标签不起作用呢?
我初学struts2,在自己新建一个工程中有如下页面:
==========================================
login.jsp

<%@   taglib   prefix= "s "   uri= "/struts-tags "   %>
<html>
<head>
<meta   http-equiv= "Content-Type "   content= "text/html;   charset=UTF-8 ">
<title> Showcase   -   Conversion   -   Populate   Object   into   Struts '   action   List </title>
</head>
<body>
<s:form>
<s:textfield   label= "userName: "   name= "userName "   />
<s:textfield   label= "password: "   name= "password "   />
<s:submit   name= "ccc "   value= "bbb "/>
</s:form>
</body>
</html>
----------------------------------
web.xml

<?xml   version= "1.0 "   encoding= "UTF-8 "?>
<web-app   id= "WebApp_ID "   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   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd ">

<display-name> mySample </display-name>

<filter>
<filter-name> struts2 </filter-name>
<filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class>
</filter>
       
<filter-mapping>
<filter-name> struts2 </filter-name>
<url-pattern> /* </url-pattern>
</filter-mapping>

<welcome-file-list>
<welcome-file> index.html </welcome-file>
<welcome-file> index.htm </welcome-file>
<welcome-file> index.jsp </welcome-file>
<welcome-file> default.html </welcome-file>
<welcome-file> default.htm </welcome-file>
<welcome-file> default.jsp </welcome-file>
</welcome-file-list>
</web-app>

----------------------------------
struts.xml

<?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= "default "   extends= "struts-default ">
<action   name= "login "   class= "com.xiangzi.LoginAction ">
<result   name= "input "> /login.jsp </result>
<result> /welcome.jsp </result>
</action>

<action   name= "append "   class= "com.xiangzi.AppendIteratorTagAction ">
<result> appendIterator_sample.jsp </result>
</action>
      </package>
</struts>

大概代码和配置如上,
我使用tomcat5.5+jdk1.5+ec3.2
当我启动服务器的时候并运行http://localhost/mySample/login.jsp
页面上竟然什么内容都没有.请高手指点

是不是标签引入错误,我也是个菜鸟
