Can I get request header info using SaxBuilder?

Hi, I've been using jdom SaxBuilder as a convenient way to get an xml response from an http request:

String url = "http://somewhere.com/request?args=vals"
SAXBuilder parser = new SAXBuilder();
Document doc = parser.build(url);

But as the request / response and parsing into xml is all done under the bonnet here, does anyone know if I can get hold of response header values that would be in the response object?

Thanks

I did it like this in the end

SAXBuilder parser = new SAXBuilder();
String url = "http://somewhere.com/request?args=vals"
URL urlObj = new URL(url);
URLConnection urlConnection = urlObj.openConnection();
urlConnection.getHeaderField("Last-Modified");
org.jdom.Document doc = parser.build(urlConnection.getInputStream());
