JSTL1.1配置

下载 jakarta-taglibs-standard-1.1.2.zip 包并解压，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 /WEB-INF/lib/ 下。

将 tld 下的需要引入的 tld 文件复制到 WEB-INF 目录下。

接下来我们在 web.xml 文件中添加以下配置：

 1 <jsp-config>
 2     <taglib>
 3     <taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>
 4     <taglib-location>/WEB-INF/fmt.tld</taglib-location>
 5     </taglib>
 6     <taglib>
 7     <taglib-uri>http://java.sun.com/jsp/jstl/fmt-rt</taglib-uri>
 8     <taglib-location>/WEB-INF/fmt-rt.tld</taglib-location>
 9     </taglib>
10     <taglib>
11     <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
12     <taglib-location>/WEB-INF/c.tld</taglib-location>
13     </taglib>

28     <taglib-location>/WEB-INF/x.tld</taglib-location>
29     </taglib>
30     <taglib>
31     <taglib-uri>http://java.sun.com/jsp/jstl/x-rt</taglib-uri>
