available");
         }
        } else {
            throw new Exception("Your mime type: " + mimeType + " is
inappropriate");
        }

    protected static boolean hasAppropriateMIME(String mimeType,
String[] mimeArray) {
        try {
            for (int i = 0; i < mimeArray.length; i++) {
                if (mimeArray[i].equals(mimeType)) return true;
            }
        } catch (Exception e) {
            System.out.println(e.getMessage());
            return false;
        }
        return false;
    }

}

And I call it like this:

 /**
     * Download the icon to a ".ico" icon
     *
     * @see ImageDownloader
     */
    public void downloadIcon() {
        try {
            if (getOrigIconFilePath() == null) generateIconFilePath();
            ImageDownloader.downloadImage(
                    toBufferedImage(getIcon()),
                    new File(getOrigIconFilePath()),
                    "image/bmp");
        } catch (Exception e) {
            System.out.println("Error trying to save icon to file: " +
e.getMessage());
        }
    }

And it works! I get a perfect 16x16 icon for Windows [can't predict if
it will work within *nix)
