Fetching iTunes RSS feed with Java

I am willing to fetch iTunes public RSS feed from a appengine java app.

In dev server, here is what I try:

URL url = new URL("http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/topsongs/limit=10/xml");
BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));

And that is the response:

<?xml version="1.0" encoding="utf-8"?> <feed xmlns:im="http://itunes.apple.com/rss" xmlns="http://www.w3.org/2005/Atom" xml:lang="en"> <id>http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/topsongs/limit=10/xml</id> <title>iTunes Store: Top Songs</title> <updated>2010-11-09T12:45:58-07:00</updated> <link rel="alternate" type="text/html" href="http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewTop?id=38&amp;popId=1"/> <link rel="self" href="http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/topsongs/limit=10/xml"/> <icon>http://phobos.apple.com/favicon.ico</icon> <author><name>iTunes Store</name><uri>http://www.apple.com/itunes/</uri></author> <rights>Copyright 2008 Apple Inc.</rights>

There is a link, "http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/topsongs/limit=10/xml", which is displayed. It is the same URL that the one I give to the java URL object...

If I open this link in the browser, I get the correct XML response.

I tried to set a different user-agent, but nothing changes.

Thanks for any help.
