String url = "http://www.netbeans.org/rss-091.xml";
//Display hardcoded URL as link under "Source:"
out.println("<u><a href='" + url + "'/>" + url + "</a></font></u></h2>");

In the project's Project Properties dialog box, I put the servlet's URL mapping (first seen in the New Servlet wizard and afterwards in the WEB-INF/web.xml file) in the Run panel's Relative URL field. As a consequence, when I deployed the application, the servlet's output was displayed in my browser. The output consisted of a text, the URL to the NetBeans RSS feed, and the content of the RSS feed which the web service had converted to HTML (click to enlarge):
If there are simpler ways to create a feedreader client, I'd like to hear about it.
