Ajax4jsf has turned one and what a year it has been. It was an amazing ride for all of us here at Exadel.

Three RIA Tools Examined: JSF, Flex, and JavaFX

2008 is going to be an important year for Rich Internet Applications. Most organizations are delivering or planning to deliver Rich Internet Applications; however, at the same time, most IT managers are facing a dilemma: which Rich Internet Application technology and platform to use? The number of different frameworks and libraries is too vast to even consider evaluating a fraction of them.  To make this task manageable, I'm going to narrow things down to three different technologies for delivering enterprise-level Rich Internet Applications.
