Apache Commons File Upload PRO

The Apache Commons open source project includes various useful components we can use in our code. One of them is the FileUpload, that allows us to develop a Java Servlet (or a JSP document) that handles files uploads.

The following video clip presents a small code sample for handling a file upload coming from an HTML file. You can find the source code as well as more explanations in the Introduction to Apache Commons course I have recently started to develop for free personal and academic usage at www.abelski.com.
