I want to make an app that uses Google Web Toolkit and Google App Engine(Java) to read RSS feed. How do I do this? Do you have any examples?
I need to retrieve first 100 strings from the RSS URL.
Thanks.

Create a GWT service with a method like:
In the implementation of that service, use GAE’s java.net.URLConnection system to get the raw XML from the RSS url. Next, you’ll need to parse that XML. You can use a plain XML parser, or use an RSS parser like Rome.
At that point, you’ve got all the data in your service, and you just need to pull out the info you want, put it into the
List<String>, and return it to the browser.
