现在不怎么做前台开发，对jstl已经很陌生了，偶尔要用的时候很多基本的东西一下想不起来，故转载本文用作备用资料。

?

一、在Tomcat中安装JSTL
前提 OS: WIN2003；Tomcat5.5；tomcat已经配置好。

1.准备jstl
?? 到http://archive.apache.org/dist/jakarta/taglibs/standard/binaries/下载jakarta-taglibs-standard-1.1.2.zip
解压后成为jakarta-taglibs-standard-1.1.2

2.准备web开发目录
?? 比如我的web目录系统默认目录%tomcat_home%\webapps\ROOT下，工作目录为ROOT,也可以自定义工作目录，但必须要保证工作目录下建立WEB-INF\lib,WEB-INF\classes

3.拷贝.jar文件
?? 将jakarta-taglibs-standard-1.1.2\lib\下的两个jar文件：standard.jar和jstl.jar文件拷贝到工作目录的\WEB-INF\lib\下

4.拷贝.tld文件
?将jakarta-taglibs-standard-1.1.2\tld\下的15个tld类型文件拷到"Working folder\WEB-INF\tld"下

5.在工作目录下的\WEB-INF\下建立web.xml文件：

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">

6.建立一个名为test.jsp文件
