input 和fmt该怎么写

soundtbugle 2009-12-29 10:45:38
我把一个对象实例(A)放到request作用域内.它有一个属性是sdate(java.util.Date)
在jsp中我想把它格式成yyyy-MM-dd的形式在input中显示.如下代码:
<input type="text" name="sdate" value="<fmt:formatDate value='${a.sdate }' pattern='yyyy-MM-dd'/>"/>

抛异常:
According to TLD or attribute directive in tag file, attribute value does not accept any expressions

web.xml的xsd
<web-app id="WebApp_ID" version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

jsp的fmt
<%@ taglib prefix="fmt" uri="/WEB-INF/fmt.tld"%>

改为：<input type="text" name="start" size="20" value=<fmt:formatDate pattern=“yyyy-MM-dd” value=“${protocol.start}” /> />

指的是这行:
<input type="text" name="start" size="20" value="<fmt:formatDate pattern='yyyy-MM-dd' value='${protocol.start}' />" />

楼主使用的是fmt-1_0.tld，1.0fmt标签库会引发楼主遇到的异常。
<%@ taglib prefix="fmt" uri="/WEB-INF/fmt.tld"%>
请检查/WEB-INF/fmt.tld的版本号是1.1以上而不是1.0
查看你使用的1.1版JSTL实现（standard.jar)或1.2版JSTL实现（jstl-impl-1.2.jar）的META-INF目录
将fmt.tld(1.1版)放到/WEB-INF目录下。

另外，最新的JSTL API及实现可以到下面的网页上下载，建议使用JSTL 1.2版。
