Wicket is a Java language Web development framework, similar to Struts, WebWork, and Tapestry. Its features include effective separation of HTML and code (favorable for cooperation between programmers and artists), rule-based configuration (reducing the use of XML and other configuration files), low learning curve (development method is similar to C/S), and easier debugging (fewer error types and easier to locate).
