請依照下述解決方式來問題排除，
1.可以到Apache Jakarta Project下載最新版本的JSTL檔，載點如下
http://jakarta.apache.org/site/downloads/downloads_taglibs-standard.cgi
亦可直接由這下載jakarta-taglibs-standard-1.1.2.zip
2.下載完成後，解壓縮，
開啟jakarta-taglibs-standard-1.1.2/lib 資料夾
複製裡面的jstl.jar和standard.jar檔案到
{Tomcat_Install}/lib 資料夾內。
3.重新啟動Tomcat，再將jsp網頁開啟將正常顯示。
參考或是複製語法時，別忘了留個言喔 ^ ^ ~
