How To Write an RSS Reader in AJAX
IBM Developers work has a tutorial on how to build an RSS reader using AJAX

From Yakov Fain's Blog

IBM Developers work has a tutorial on how to build an RSS reader using AJAX.  The amount of code you need to write is scary (and this is not the complete code). Adobe Flex 2 plus a simple Java programming to support DB interaction allows you to achive the same functionality using A LOT LESS coding.Just  take a look at this screen:

The Flex 2 code  below populates the bottom portion of the screen with financial news based on the selected stock on top ( (it does not work with a DB to store the RSS source so it'd add some 50 lines of  Java code ). The data come from the Yahoo! Finance RSS feed. The URL looks as follows: http://finance.yahoo.com/rss/headline?s=MSFT
The suffix can be MSFT or whatever is selected on top is being passed to the code below.  
Flex <mx:HTTPService> object is used through  a proxy deployed under Tomcat or any other servlet container.
The entire application code and its description can be found in this article.
