We can read RSS (Real Simple Syndication) feeds and publish them on our web page using JSP(Java Server Pages) tag library. Sun provides a rss taglib that can be used in JSP. It is extremely simple to use. You just need to have basic knowledge of JSP and HTML.
So, how to do that? First you need to download the tag library file (rssutils.tld, rssutils.jar) from Sun’s website. Here is the url to download it. Put the files rssutils.tld and rssutils.jar in WEB-INF/lib directory of your web application.
After that, choose a blog or website who publishes its rss feeds to users, and get the url of its rss feed. In below example, I have used the rss feed url of this blog. Please find the attached file here and save it with .jsp extension (rssTest.jsp)
You can use tag also to read content in a loop.
