RSS是一个标准的XML文件，Rss阅读器可以读取这个XML文件获得文章的信息，使用户可以通过Rss阅读器

而非浏览器阅读Blog，我们只要动态生成这个XML文件便可以了。RSSLibJ是一个专门读取和生成RSS的小

巧实用的Java库，大小仅25k，可以从[url]http://sourceforge.net/projects/rsslibj/[/url]下载rsslibj-

1_0RC2.jar和它需要的EXMLjar两个文件，然后复制到web/WEB-INF/lib/下。

rsslibj-1_0RC2.jar下载地址： [url]http://sourceforge.net/project/downloading.php?group_id=71153&use_mirror=nchc&filename=rsslibj-1_0RC2.jar&27763931[/url]

EXML.jar下载地址：[url]http://rsslibj.cvs.sourceforge.net/rsslibj/rsslibj/lib/EXML.jar?view=log[/url]

下载下来之后把扩张名.zip 改为 .jar 就行了。
