Just got back from Boston after being there for 3 days for Eclipse World 2006. I had two session, Leveraging JSF Components and Building Rich Internet Applications with JSF and AJAX. After chatting with people at the conference, one thing is for sure, more and more companies are choosing JSF as the framework to build enterprise Web applications. I also had a chance to chat with Jonas Jacobi (author of Pro JSF and AJAX), he basically said the same thing, more and more companies are using JSF. Virtually any new Web project is using JSF today.
