Unable to acquire image through ImageIO.read(url) because of connection timed out

Question

The following code always seems to fail:

    URL url = new URL("http://userserve-ak.last.fm/serve/126/8636005.jpg");
    Image img = ImageIO.read(url);
    System.out.println(img);

I've checked the url, and it is a valid jpg image. The error I get is:

Exception in thread "main" javax.imageio.IIOException: Can't get input stream from URL!

What does this mean? Funny thing is, if I change my internet-connection to that of the neighbour's wireless, it suddenly works.

Answer 1

This worked for me. :)

URL url = new URL("http://userserve-ak.last.fm/serve/126/8636005.jpg");
Image image = ImageIO.read(url.openStream());
System.out.println(image);

I know I am late. Since, even I faced the same issue, thought of putting as it would help some one. :)

Answer 2

This is maybe unlikely on a home network, but a lot of companies have HTTP proxy servers that can make your errors a little misleading. Often the URL will appear to work fine manually because your browser is configured to use your proxy server. You can set the proxy settings on the command line or in the code, see: http://java.sun.com/javase/6/docs/technotes/guides/net/proxies.html.
