You cannot create a file on the local machine using an applet. Java security manager does not allow this.

No you cannot create a text file on a local machine using Javascript or HTML. But I think you can create a text file using a signed applet using JDK 1.2. When the user requests a page containing this applet, the browser asks the user whether or not to download the applet and give permission to create a file. If the user agrees, then the applet can create a text file. Otherwise no.

Yes, how can I use a signed applet ?
How must I use the security manager to ask the user?

I haven't tried it yet myself, but this looks like a good site for the information you want:
http://java.sun.com/security/signExample/index.html
Hope it helps. Let us know.
