ZK Description

Open-source Ajax Web framework that enables rich user interface for Web applications with little programming The event-driven engine brings the intuitive desktop programming model to Web developers. The XUL and XHTML components enrich Web applications by off-the-shelf building blocks. The markup language, called ZUML, makes the design of rich user interfaces as simple as authoring HTML pages.ZK is an open source Web development framework that enables Web applications to have both rich user experiences and low development cost as you did for years in desktop applications. ZK includes rich sets of XUL and XHTML components, an Ajax-based event-driven engine, and a markup language. Here are some key features of "ZK": · Over 70 XUL and 80 XHTML components are supported, including list boxes, tree, drag-and-drop, auto-completion, sliders, timer, combo boxes, audio and many others. · Server centric. Visual representation and content are synchronized automatically between clients and servers. The best way to use Ajax is not to know its existence. · Script in Java and EL expressions. No JavaScript. No compilation. No proprietary expressions or scripts. · Simple threading model. No prerequisite of handling threading and concurrent accesses. Yet no limitation to apply any sophisticated threading on your demand. · Flexible threading model. Easy to suspend and resume your application without blocking users. Supports true server-side modal dialogs. · Easy to develop new components with supports of template and synchronization technologies. · Easy to encapsulate a pure-client JavaScript widget into a server-centric Java component, such as FCKeditor and Dojo. · Easy to power applications with versatile components, as simple as dropping jar files into the class path. · An open community to share components, themes and utilities. · Zero configurations and compilation. Maintaining ZUML pages is as easy as maintaining HTML pages. · No prerequisite of any design patterns. For fast protyping, you could embed Java codes directly in ZUML pages. For sophisticated applications, you could apply MVC or others. The choice is yours, not framework. Requirements: · Internet Explorer 6+/7, Firefox 1+, Safari 2+, Mozilla 1+, Opera 9+ or Camino 1+ · Any Web server that supports Servlet 2.3+ and JVM 1.4+ What's New in This Release: · The main focus of ZK 3.6.2 was improving performance, especially in IE6. · In addition to the great strides in performance 48 bugs have been fixed and more powerful features have been introduced, such as more include modes, support for Google App Engine and script and initialization tag improvements!
