I am a server side guy.. I have no much expertise in GUI technologies,
but JSF 2.0 Facelets seems a very promising technology..
I am following a parallel "HTML+CSS+jQuery" GUI done by a student
under my supervision.. but over there I missed a set of basics
features like validation, navigation, etc.. and that's why I started
my self investigation about JSF 2..
The best of my pet project continues to be the server side but
eventually my several frontends will bring me a better feeling on how
this technologies integrates to my web-services ;)
so far I have:
DWR frontend:

JSF 2.0:
http://fgaucho.dyndns.org:8080/arena-jsf20/
both GUIs connected to the same backend: a EJB 3.x + JPA 2 + Jersey
REStful web-services
let's see.. a lot to learn, a lot to enjoy :)
