ZK_Arch_notes_20081121

ZK is a model-view-controller framework for building desktop-like web applications using ZUML, ZScript, and Java. It uses a servlet-based architecture where ZK Loader handles initial page loads and the AU Engine handles AJAX requests. The ZK library is included in the webapp and generates the necessary folder structure and files. Developers define the web application using ZUML and deploy it by copying the compiled files into Tomcat's webapps folder.
