As you probably know JSF 2 is a major upgrade over JSF 1.2. One of the major additions to this version of JSF is standard Ajax support. This article covers Ajax features in JSF 2. If you are familiar with RichFaces and specifically the a4j:support tag then learning how to use Ajax features in JSF 2 is going to be very easy. Many concepts and features are being carried over from RichFaces.  Let’s start.  JSF 2 comes with one tag that provides Ajax functionality. The tag is called f:ajax (sounds familiar to a4j:support – right?) When I do RichFaces trainings, I like to divide the core ideas into three parts: sending an Ajax request, partial view rendering and partial view processing. I will use the same approach here.

How to Highlight a Field in JSF When Validation Fails

Highlighting an input field that failed validation (or conversation) is a common UI practice today. This sort of functionality is not available in JSF (nor RichFaces) out of the box (Seam does have it). I got an email from RichFaces 4 workshop attendee from CONFESS_2011 conference asking how to do it and I thought it’s a good idea to make it blog post.
