struts2.1.6的一个问题怎么办

Unterminated <%@ taglib tag是啥意思？jsp程序如下：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>UI Tags Example</title>
<s:head />
</head>
<body>
<table>
<s:form id="id" action="Reg">
    <s:textfield name="username" label="%{getText('username')}"/>
    <s:password name="password1" label="%{getText('password1')}"/>
    <s:password name="password2" label="%{getText('password2')}"/>
    <s:datetimepicker name="birthday" label="%{getText('birthday')}" displayFormat="yyyy-MM-dd"></sx:datetimepicker>
dd"></sx:datetimepicker>
    <s:submit value="注册"/>
</s:form>
</table>
</body>
</html>
在IE中打开错误如下：
