FileNotFoundException while reading RSS in Android

Question

I am trying to read an RSS feed. I have tried many links using the code below and succeeded, but when I try with that link above I get a FileNotFoundException. What could cause this, and how do I fix my code?

try using HTtpConnection instead of URLConnection, as follows:

InputStream callWebErvice(String serviceURL){
        // http get client
            HttpClient client=new DefaultHttpClient();
            HttpGet getRequest=new HttpGet();

            try {
                // construct a URI object
                getRequest.setURI(new URI(serviceURL));
            } catch (URISyntaxException e) {
                Log.e("URISyntaxException", e.toString());
            }

            // buffer reader to read the response
            BufferedReader in=null;
            // the service response
            HttpResponse response=null;
            try {
                // execute the request
                response = client.execute(getRequest);
            } catch (ClientProtocolException e) {
                Log.e("ClientProtocolException", e.toString());
            } catch (IOException e) {
                Log.e("IO exception", e.toString());
            }
            if(response!=null)
                return response.getEntity().getContent();
            else
                return null;

    }

and change line xr.parse(new InputSource(url2.openStream()));

to

xr.parse(new InputSource(callWebErvice(url2)));
