How to check Returned Server Code Using DOM?

Question

I am getting data from a REST based web service outputting data in XML format. As I am using DOM and later parsing it to a doc using the DocumentBuilder I am not able to get the server's HTTP Status Code if there is any error.

So, is it Possible to return the HTTP Status Code?

Here is a little snippet:

url = "MY_URL";
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new InputSource(url.openStream()));
doc.getDocumentElement().normalize();

Any advice is much appreciable.
Thanks

it's pretty obvious ... 200, 404 ...http://stackoverflow.com/questions/6467848/how-to-get-http-response-code-for-a-url-in-java — Selvin, Apr 03 '13 at 07:25
Response code of successful web service call or code returned by webservice? — Paresh Mayani, Apr 03 '13 at 07:25
AFAIK, response code is basically "the code returned from a server". Like Selvin has given above^ 404,200, 805. Moreover you can say the `HTTP Status Code` :D Please see my updated ques. — beerBear, Apr 03 '13 at 07:27

You should do a bit changes in your code to do so:

URL url = new URL("MY_URL");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
Document doc = dBuilder.parse(new InputSource(connection.getInputStream()));
doc.getDocumentElement().normalize();
int code = connection.getResponseCode();

url.openStream() will throw an IOException indicating the error if some problem occurs. Check the exception message/cause for details of the error.
