Read a file in clientside, javascript, java applets

I'm trying to write a web-based application where a JavaScript has to read a file from the client's computer and upload the data to a file in the server.

It was when I was going through the net that I found that JavaScript is not able to do this.

I found this site but I cannot understand any of it. Looks as if incomplete to me. Maybe becau开发者_开发问答se I'm just a starter.

Can somebody give me some help here?

Thanks in advance.

Why don't you use the HTML5 FileSystem API ?

A good wrapper around it has been released recently "filer.js"
