[file upload] flow, actions and ........ XSP ?

[St�phane Delort]

Thanks to Askild; I finaly reached my goal.

but I for doing this file upload I uses neither flows nor actions, but a
"simple" XSP page.  
(source code copied at the end)

I would like to know the differencies between doing that with actions,
flows and XSP. 


thanks in advance,
Stephane
