“OpenLaszlo is a rich client application architecture that uses Macromedia to build Flash widgets with XML and JavaScript logic. This article details the basic concepts of OpenLaszlo, and gives examples of situations in which an OpenLaszlo solution might be beneficial and it also details how it compensates for the shortcomings of Ajax dynamic web development.”
The article doesn’t appear to compare Laszo against Flash (or Flex, its real competitor), but DHTML/AJAX.
I’m guessing a bit here, but I think that the headline tries to express how this Laszlo uses the “advantage of Javascript” and that it works over a layer of Flash (over as in “Voice over IP”).
AJAX+DHTML rocks. I’m going to try coding a web app using AJAX+JSP. Looking at code presented in article, you can pretty easily code application logic and user interfaces.
