Here, some code that you can use to file upload. This code use o'reilly's
jar.
The package is: package com.oreilly.servlet
text of licence:
18 September 1998
This is the README file for the com.oreilly.servlet package.
------------------------------------------------------------
The com.oreilly.servlet package contains a set of (what I hope to be) useful
utility classes for servlet developers. Included are classes to help
servlets parse parameters, handle multipart requests (file uploads),
generate multipart responses (server push), negotiate locales for
internationalization, return files, manage socket connections, and act as
RMI servers, among other things. There's even a class to help applets
communicate with servlets.
Why did I write these classes? They started out as chapter examples in my
book Java Servlet Programming being published by O'Reilly & Associates. Then
one happy day I recognized they could, with a little modification, live on
their own as reusable utility classes. That day, or maybe a few
procrastinating days later, com.oreilly.servlet was born.
The classes in the com.oreilly.servlet package have existed in their current
form more or less unchanged since April 1998. In the six months since April,
they have been widely distributed for testing purposes, but I've kept the
package in official "beta" until now to time its release with the book
release. The reward for everyone's patience is that the classes already have
been widely tested on a multitude of platforms and server configurations,
and you should find this a very stable 1.0 release.
I hope you enjoy using these classes and that they help you write more
powerful and elegant servlets.
