ZK, an open source Asynchronous JavaScript + XML (Ajax) framework written in Java™ code, lets you write a Web 2.0-enabled, rich Internet application without writing a single line of JavaScript code. Typical Ajax frameworks like Dojo have JavaScript libraries that expose certain API's for making "Ajaxified" calls. ZK, on the other hand, uses a meta-definition based on XML to define the user interface. Translation to HTML code then occurs when this page is requested by the client. This article introduces you to ZK and gives you a real-world example of its use running on Apache Tomcat and connecting to a MySQL database.
