Java Forum / General / January 2006Getting http response code
Quick question -- If I do url processing such as: try { URL url = new URI(address).toURL(); InputStream is = url.openStream(); } catch (IOException x) { . . . } is there a way in the catch block to get the http response code (eg: 404) if there is one? > Quick question -- If I do url processing such as: > [quoted text clipped - 7 lines] > is there a way in the catch block to get the http > response code (eg: 404) if there is one? url.openStream() is shorthand for url.openConnection().getInputStream(). You need to get the URLConnection to get the response code. Try using the two separate methods, like HttpURLConnection connection = (HttpURLConnection) url.getConnection(); InputStream is = connection.getInputStream(); You can then use connection.getResponseCode() to get the response code and use the fields of HttpURLConnection to determine which code you have.

If you use URL.openConnection, it shouldn't actually connect straight away. Cast the URLConnection to HttpURLConnection (assuming you had an http or https URL). When you use the connection you might get an exception (the exact behaviour changed at some point, IIRC), but still have access to the original connection object.
