				Method openURL = Class.forName("com.apple.eio.FileManager").getDeclaredMethod("openURL",
						new Class[] { String.class });
				openURL.invoke(null, new Object[] { url });
			} else if (osName.startsWith("Windows")) {
				Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
			} else { // assume Unix or Linux
				String[] browsers = { "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" };
				String browser = null;
				for (int count = 0; count < browsers.length && browser == null; count++) {
					if (Runtime.getRuntime().exec(
							new String[] { "which", browsers[count] }).waitFor() == 0) {
						browser = browsers[count];
					}
				}
				if (browser == null) {
					throw new Exception("Could not find web browser");
				} else {
					Runtime.getRuntime().exec(new String[] { browser, url });
				}
