index.jsp代码如下：

 <%@ page language="java" contentType="text/html; charset=UTF-8"
     pageEncoding="UTF-8"%>
 <%@ taglib prefix="s" uri="/struts-tags" %>
 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 <html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <title>Insert title here</title>
 </head>
 <body>

            <s:form action="testConversion">
                     <s:textfiled name="age" label="Age"></s:textfiled>
                     <s:submit></s:submit>
            </s:form>

 </body>
 </html>

原因分析：

看报错信息： No tag "textfiled" defined in tag library imported with prefix "s"，以s为前缀的标签库里不存在“textfiled”标签的定义。

检查<s:textfiled>标签,发现拼写错误。应该是<s:textfield>

解决办法：把<s:textfiled>标签改成<s:textfield>
