What is the best regular expression to check if a string is a valid URL

Is there a way to see if a string is a valid URL? I'm using MIDP library and there are not regular expressions in MIDP. Any help is greatly appreciated.

Why not just construct a java.net.URL out of the string and catch any exceptions that might be thrown?

String something;
try {
  URL url = new URL(something);
} catch (MalformedURLException e) {
  // it wasn't a URL
}
