It is very likely that you are within a network where you are not allowed to connect directly to anything port 80; try and:

telnet www.novell.com 80

and see if you get an answer; this will probably result in a timeout as well.

More likely than not you need to use a proxy (see here for instance). Also, your code leaves many resources dangling, and you use File which is obsolete.

Here is how to do it in modern code:

final Path dstfile = Paths.get("h:", "abc.zip");

// ...

try (
    final InputStream in = url.openStream();
) {
    Files.copy(in, dstfile, StandardOpenOption.CREATE_NEW);
}
