Hi all,

I am developping a Web application with Servlets/JSP and Javascript, and I have the following requirement:
On the client(user) of the Web application,there is a scanner which
is connected to the client machine and when the user puts a document (such as a paper containing text and images) on the surface of the scanner, he can click on a button on a form of the Web application and this click must trigger the scanning process and the file resulting of the scanning must be placed in a folder of the client machine (let's say this folder is D:\Images).
Please , how can I solve this problem using Javascript??
Thanks you in advance for your answers.

You can't.

You'll need something active on the client such as an Applet.
