Hello to all,

I want to upload a directory to the server using jsp/jsf component. So, how can I browse to the directory?

Thanks in advance.

The contents of the directory or the directory alone ?

I want to upload the content of the directory with directory.
Suppose there are 20 files in the directory, I want to upload the those 20 file.

Uploading the directory isn't the problem. Selecting all the files in the directory is. I'm using a RichFaces JSF control to do multi-file uploads, but the user has to select each file individually.

Manual file selection is mandated because making it too automatic would permit people to design malware that bulk-uploaded files with sensitive information in them. The only way I can think of to get around this would be to initiate the uploaded from JavaScript, but JavaScript's sandbox may not permit selection without user interaction for the reason I just gave.

Actually, there's one way that definitely would work, and that's to run a true client-side application such as a Java applet. But in order to make the applet capable of uploading, you'd have to digitally sign it, since unsigned applets aren't allowed to access the user's local filesystem. And getting signed applets accepted by the user's browser is more pain than casual Internet users are generally willing to put up with.
