regular expressions, characters unallowed in file names

[chop ficaro]

trying to take a url and turn it into a file name by grabbing the last bit of the string that doesnt have any characters that arent allowed in file names, but this keeps returning "://" and slashed, all the charqacters i DONT want

System.out.println("\n" + filename + "\n");
Pattern pattern = Pattern.compile("[^[\\\\/:\\*\\?\\\"<>\\|]]+");
Matcher matcher = pattern.matcher(filename[i]);
while (matcher.find()) 
{
  filename = matcher.group();
  System.out.println("\n" + filename + "\n");
}

What about this?

 String url = "http://www.math.uio.no/faq/compression-faq/part1.html";
 System.out.println( new File( new URL(url).getPath() ).getName() );
