how to upload a file using servlet

[simon]

I want to write a servlet to upload a file
I read about jakarta project's commons file upload but can any body please guide me how to use it by sending some sample code?

The com.oreilly.servlet.MultipartRequest class is order-of-magnitude easier to use than Jakarta fileupload:

Servlets.com | com.oreilly.servlet

You instantiate an object, then the uploaded file is on your disk at your server machine. The class is just like a vending machine for file upload. For commercial use, however, you have to buy author's book or books.
