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> 14 <taglib> 15 <taglib-uri>http://java.sun.com/jsp/jstl/core-rt</taglib-uri> 16 <taglib-location>/WEB-INF/c-rt.tld</taglib-location> 17 </taglib> 18 <taglib> 19 <taglib-uri>http://java.sun.com/jsp/jstl/sql</taglib-uri> 20 <taglib-location>/WEB-INF/sql.tld</taglib-location> 21 </taglib> 22 <taglib> 23 <taglib-uri>http://java.sun.com/jsp/jstl/sql-rt</taglib-uri> 24 <taglib-location>/WEB-INF/sql-rt.tld</taglib-location> 25 </taglib> 26 <taglib> 27 <taglib-uri>http://java.sun.com/jsp/jstl/x</taglib-uri> 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> 32 <taglib-location>/WEB-INF/x-rt.tld</taglib-location> 33 </taglib> 34 </jsp-config>
