• 复制一个 jstl.jar 和 standard.jar 包到 WEB-INF/lib 下。

• 把 tld 文件的目录也复制到 WEB-INF 中

修改 web.conf，配置 taglib：

<jsp-config> 
   <taglib> 
    <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri> 
    <taglib-location>/WEB-INF/c.tld</taglib-location> 
   </taglib> 

   <taglib> 
    <taglib-uri>http://java.sun.com/jsp/jstl/xml</taglib-uri> 
    <taglib-location>/WEB-INF/x.tld</taglib-location> 
   </taglib> 

   <taglib> 
    <taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri> 
    <taglib-location>/WEB-INF/fmt.tld</taglib-location> 
   </taglib> 

   <taglib> 
    <taglib-uri>http://java.sun.com/jsp/jstl/sql</taglib-uri> 
    <taglib-location>/WEB-INF/sql.tld</taglib-location> 
   </taglib> 
</jsp-config>
