java.io.FileNotFoundException for valid URL

I use library rome.dev.java.net to fetch RSS.

Code is

URL feedUrl = new URL("http://planet.rubyonrails.ru/xml/rss");
SyndFeedInput input = new SyndFeedInput();
SyndFeed feed = input.build(new XmlReader(feedUrl));

You can check that http://planet.rubyonrails.ru/xml/rss is valid URL and the page is shown in browser.

But I get exception from my application

java.io.FileNotFoundException: http://planet.rubyonrails.ru/xml/rss
        at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1311)
        at com.sun.syndication.io.XmlReader.<init>(XmlReader.java:237)

        at java.lang.Thread.run(Thread.java:619)

I don't use any proxy. I get this exception on my PC and on the production server and only for this URL, other URLs are working.

java url rss ioexception rome

I tried this code

HttpClient httpClient = new DefaultHttpClient();
HttpGet pageGet = new HttpGet(feedUrl.toURI());
HttpResponse response = httpClient.execute(pageGet);
SyndFeedInput input = new SyndFeedInput();
SyndFeed feed = input.build(new XmlReader(response.getEntity().getContent()));

It works! Thank for your suggestions. Looks like this is about user-agent.
