1：Java Rss開源組件包很多，

如RSSLibJ、RSSLib4J、RSS Reader、FaceRSS等等，

本文使用rssutils.jar，Sun網站有提供下載。

2：用Myeclipse建WebProject,Jar 放入lib中，tld放入WEB-INF下

3：web.xml

<? xml version = "1.0" encoding = "UTF-8" ?>

<! DOCTYPE web-app PUBLIC "-//Sun Microsystems,

Inc.//DTD Web Application 2.3//EN"

"http://java.sun.com/dtd/web-app_2_3.dtd" >

< web-app >

< taglib >

< taglib-uri > /WEB-INF/rssutils.tld </ taglib-uri >

< taglib-location > /WEB-INF/rssutils.tld </ taglib-location >

</ taglib > </ web-app >

4:index .jsp

以CSDN為例，去網站找到Rss xml http://dev.csdn.net/rss/2.xml

<%@ page language = "java" import = "java.util.*"

pageEncoding = "BIG5" %>

<%@ taglib uri = "/WEB-INF/rssutils.tld"

prefix = "rss" %>

< html >

</ head >

< body >

< rss:feed url = "http://dev.csdn.net/rss/2.xml"

feedId = "csdn" />

< b > Image: </ b >

< rss:channelImage feedId = "csdn" />

< br >

< b > Title: </ b >

< rss:channelTitle feedId = "csdn" />

< br >

< b > Link: </ b >

< rss:channelLink feedId = "csdn" asLink = "true" />

< br >

< b > Description: </ b >

< rss:channelDescription feedId = "csdn" />

< br >

< ul >

< rss:forEachItem feedId = "csdn" >

< li >

< rss:itemDescription feedId = "csdn" />

</ rss:forEachItem >

</ ul >

</ body >

</ html >

5：部署、訪問 OK.
