how to parse all the files in the directory entered by a web form?
Posted on 2004-10-14
dear experts,
i have a web page which allows users to enter a directory of their local machine. after user "submit" the entry, my application will parse all the files in the directory.
I am thinking of using Upload and then File Process. However, I can only find how to upload file, not a directory with all the files in the directory. Please help. thanks.

Hi dodowoman,
Do you need the files on the server for any other purpose than to parse and process? I.e. do you need to store those files, or are you simply providing a result back to the client?
If you don't need to store the files on the server, I would suggest using a signed applet for two reasons: 1. there is no file transfer involved, 2: no server resources are required for processing the files as the processing is done on the client.
Cheers!

thanks.
yes, I don't need the files,but only the results.
Is there an example that you could point it out to me? thanks again.

dodowoman,
I don't have a specific example of how to do the things you want to do, but here are some good resources:

orangehead911,
Here's an example for signing an applet:
http://java.sun.com/developer/onlineTraining/Programming/JDCBook/signed.html
You need to sign the applet in order to gain access to the local file system. An applet runs in what is called a sandbox, and is not allowed by default to open network connections to hosts other than the one it came from, nor is it allowed to read/write files.

You'll *have* to use a signed applet. Browsers don't support uploading multiple files, unless you place n controls for n files on the form
