ItsNat, Natural AJAX

ItsNat is an innovative open source (dual licensed GNU Affero General Public License v3/commercial license for closed source) Java AJAX Component based Web Framework. It offers a natural approach to the modern Web 2.0 development.

ItsNat simulates a Universal W3C Java Browser in the server; the server mimics the behavior of a web browser, containing a W3C DOM Level 2 node tree and receiving W3C DOM Events using AJAX. Every DOM server change is automatically sent to the client and updated the client DOM accordingly. Consequences: pure (X)HTML templates and pure Java W3C DOM for the view logic. No JSP, no custom tags, no XML meta-programming, no expression languages, no black boxed components. The developer has the full control of the view.

Since 0.7 ItsNat supports remote XUL applications.
