JSTL的时间格式化标签的使用

JSP Standard TagLibraries 

Formatting and Internationalization 
Two form input parameters, 'date' and 'isoDate', are URL-encoded inthe link leading to this page. 'isoDate' is formatted according tothe ISO8601 standard. 
Formatting of numbers and dates is based on the browser's localesetting. Formatting will change if you switch the default languagesetting from English to French or German, for example. (The browserneeds to be restarted, too.) 

Library import and parameter capturing: 

<%@ taglib prefix="c"uri="http://java.sun.com/jstl/core"%> 
<%@ taglib prefix="fmt"uri="http://java.sun.com/jstl/fmt"%> 

<fmt:parseDate value="${param.date}" var="date"pattern="yyyy/MM/dd:HH:mm:ss> 
<fmt:parseDate value="${param.isoDate}"var="isoDate"pattern="yyyyMMdd'T'HHmmss"> 

The input parameters must match the patterns, or the JSP willthrown an exception. This page does no errorhandling.
