Hi,

Can someone show me how to retrieve a directory listing from web. Example, given that

 www.mypage.com/thumbnails/

is a directory contains images, how do I get a similar action as File.List() call which shows me all the filenames of this directory?

I want to write a little applet that shows a slideshow of all the images stored on my site but I dont want to update a textfile everytime an image or file is added on!

Thanx

You can't, unless the web server has been set to perform a default listing of files. If it has, you can parse the html returned, e.g.

http://www.proteanit.net/misc/

but the server could have been cconfigured to return an error page

I'm looking at the possibility of JavaScript.FileSystemObject which can returns "file" objects. Appreciate if you could let me know if this is good idea? can we pass Javascript objects to applets?

What does it mean to be "Always On"?

Oh ftp is OK yes, if you've got a server running. That will support file listing and retrieval. I though the FileSystemObject was VB but i could be out of touch ;-)

Yep, it's VB all right! AFAIK this is OK, but it hasn't got much to do with Java

No that will not help you.

> Can someone show me how to retrieve a directory listing from web

If you are managing the server then easiest would be to keep a file in the directory containing the contents and diwnload that file.

Thanx guys. feeling a bit floaty right now after watching Hero. Anyway

CEHJ: What does AFAIK mean?

Object: >If you are managing the server then easiest would be to keep a file in the directory containing the contents and diwnload that file.

This is what I'm doing right now with a text file contains all the file names/path.

The reason I suggested javascript is that I'm thinking of dynamically write a html file contains all the file names as Applet parameters then load them into my applet.

My files reside in geocites.com, so I think that itself is a server that allows client ftp connections. Maybe FTP can be used in this case, alternatively to above.

So guys if you can suggest me as many alternatives as you can think of, it would be much appreaciated. A Learning curve here :)

That would be the best. A text file would need to be kept in synch

thats another option if you dynamically create the html.

> Maybe FTP can be used in this case, alternatively to above.

sure, I thought you said earlier you couldn't use it.


you can use whatever server side technology is available to you.
