  1. public class TestURLProtocol {

  3.     public static void main(String[] args) {
  4.         String host = "";
  5.         String file = "/index.html";
  6.         
  7.         String[] schames = {"http", "https", "ftp", "mailto", "telnet", "file", "ldap", "gopher",
  8.                  "jdbc", "rmi", "jndi", "jar", "doc", "netdoc", "nfs", "verbatim", "finger", "daytime", ""
  9.                         + "systemresource"};
  10.         for (int i= 0; i < schames.length; i++) {
  11.             try {
  12.                 URL url = new URL(schames[i], host, file);
  13.                 System.out.println(schames[i] + " is supported\r\n");
  14.             } catch (MalformedURLException e) {
  15.                 // TODO Auto-generated catch block

  17.                 e.printStackTrace();
