RSS是一個標準的XML文件，Rss閱讀器可以讀取這個XML文件獲得文章的信息，使用戶可以通過Rss閱讀器
而非瀏覽器閱讀Blog，我們只要動態生成這個XML文件便可以了。RSSLibJ是一個專門讀取和生成RSS的小
巧實用的Java庫，大小僅25k，可以從
http://sourceforge.net/projects/rsslibj/
下載rsslibj-
1_0RC2.jar和它需要的EXMLjar兩個文件，然后復制到web/WEB-INF/lib/下。

rsslibj-
1_0RC2.jar
下載地址：
http://sourceforge.net/project/downloading.php?group_id=71153&use_mirror=nchc&filename=rsslibj-1_0RC2.jar&27763931
?
下載下來之后把 擴張名.zip 改為 .jar 就行了。
