工作总结

1 The absolute uri: http://java.sun.com­/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application  I changed "http://java.sun.com/jsp/jstl/core" to "http://java.sun.com/jstl/core，run OK

2 According to TLD or attribute directive in tag file 引用jstl 包 版本不对
jsp2.0 自定义tags 今天自己写咯一个，感觉还不错哟～～继续加油哟

jstl基本语法<c:set value="" var=""></c:set>

<c:foreach></c:foreach>

<<c:set var="" value=""/>

<c:foreach>

<c:choose>

<c:when>

<c:otherwise>

<c:if test>

<c:when></c:when>

<c:otherwise></c:otherwise>

<c:if test=""></c:if>
