Server side web frameworks are dead. Long life to client side web frameworks. Struts, JSF, Spring, Ruby on Rails, Cake, Symfony … (even my framework in PHP 😉 ) as full stack web framework are dead. Logic is moving to the client side. Javascript, the language used as deadly weapon in the browser wars nowadays is the key of the web. Server logic is getting thin.
