Hello twittwit and others, I've been trying to implement file upload for days in my application. It may looks stupid but I really don't understand how it works. I have few questions: - If I want to use the same code as twittwit where should I place it? in my client folder or server folder? should I add something else in my web.xml and project.gwt.xml files?
I'm completely lost, please help me!
