Retrieve file/directory listing from a URL

Question

I am building an applet to view images located on a given URL (not the same as the codebase URL...). The problem is how to see which directories and files that are located on the given URL? File.list() works fine as long as I'm the pictures are located on my own computer, but I would like to do something like:
File f = new File(new URL("http://.../imagelibrary"));
String [] x = f.list();
Please help me out!
You'll get credited for it - I promise!

Hi,
I make a try to help you. A applet has only a HttpConnection to the server. Typical over this connection you can receive a file. E.g., when you connect the http-server by a browser, you becomes a html-page, with a table or list from the directory,when it allowed. Over a HttpURLConnection you can receive this html-code by the following code-snippet:public class DownLoad {
     public static void main(String args[]) {
          try {
               java.net.URL url = new java.net.URL("http://localhost:8080/../images/");
               java.io.InputStream in = url.openStream();
               int count = in.available();
               byte content[] = new byte[count];
               in.read(content, 0, count);
               String contentAsString = new String(content, 0, count);
               System.out.println(contentAsString);
          } catch (Exception e) {
               e.printStackTrace();
}Now you can show this in the applet directly or you parse the contentAsString and find the entry in the table/list.
Hope thats help
