Uploading multiple files in one go without zipping them up, can be achieved using the following two obvious solutions :
Let's see the second solution while using Stripes with SWFUpload.
Eclipse in this case is the IDE. The object of this guide not being to go into any details of Eclipse, I consider the reader to be familiar with said IDE.
The Maven2 plugin is used with Eclipse.

To keep it simple, I've used source code from the simpleExample of the on-line demo at SWFUpload.
