ItsNat Natural AJAX, is an open source Java component-based Ajax framework.ItsNat is server centric using an approach called TBITS, "The Browser Is The Server". ItsNat simulates a Universal W3C Java Browser at the server containing a W3C DOM Level 2 node tree and receiving W3C DOM events.When the server DOM tree is modified using Java W3C DOM APIs by the developer, this modification is detected (firing DOM mutation events) and automatically sent to the real web browser as JavaScript DOM based code, synchronizing the client DOM accordingly, usually as response of an AJAX event (ItsNat is heavily based on AJAX).
