com.sun.syndication.io.SyndFeedInput input = new com.sun.syndication.io.SyndFeedInput();

com.sun.syndication.feed.synd.SyndFeed feed = input.build(new com.sun.syndication.io.XmlReader(feedUrl));

%>

<%=feed.getTitle()%>

java.util.List list = feed.getEntries();

for (int i = 0; i < list.size(); i++) {
