GWT
I liked GWT from it's first days.
Now, after more than three years (I started using it in a PRODUCTION project in summer 2006) I think it as a mature framework to develop AJAX web application without using the horrible JavaScript language.
In this section I published these articles (beyond all the articles I publisher on my jroller blog)
This contains my presentation of GWT 2.0 at local GTUG
Instead here I talk about using Google Spreadsheet as DataSource for our GWT applications.
