Extracting Image from Internet

Question

Hi,
Am trying to extract an image from a URL as follows:
try
BufferedImage input = ImageIO.read(new URL("http://www.google.co.in/images/close_sm.gif"));
File outputFile = new File("image.png");
ImageIO.write(input, "PNG", outputFile);
catch(Exception e)
System.out.println(e);
}The URL is a valid one. But still I get the following error :
javax.imageio.IIOException: Can't get input stream from URL!Any idea where I am going wrong ?
Thanks for any help ..

Hi ashokkumar!
Doc says there isn't an registered ImageReader!?!?
Circumvent the problem obtaining an input stream from a HttpURLConnection via method getInputStream:
HttpURLConnection conn = new HttpURLConnection(
new URL("http://www.google.co.in/images/close_sm.gif"));
conn.setRequestMethod("GET");
conn.connect();
BufferedImage input = ImageIO.read( conn.getInputStream() );
conn.disconnect();
If still find exceptions, check the connection response code
code = conn.getResponseCode();
and try to "negotiate" with server via HttpURLConnection methods like:
conn.setRequestProperty("User-Agent", yourUserAgent);
This (sometimes) helps to avoid "deny of service" on HTTPD server against some kind of requests.

P.S.: They try...we always sniff.
