Introduction

Before starting up Wicket, we were checking the available versions. The latest one is 6.9. It is clearly mentioned in the Apache Wicket site that the latest projects should use Version 6.9 as the base. We have NetBeans 7.1 after downloading the Wicket plugin for net beans. We found that the net beans Wicket plugin supports Version 1.5 of Wicket.

We prefer using the latest stable version; it will have many bug fixes and upgrades and will make it easier to develop.

Wicket also uses the Wicket filter to dispatch requests and responses. Just as with GWT and Vaadin applications, which had servlet, which expected some parameters such as UI class to get initialized, we need to provide a class name of the class that extends the Web Application class as a parameter to the filter. Then there are classes, which extend the WebPage class. It's a good convention and practice to create an HTML page with the same name as the class that extends the WebPage class.

Wicket uses the multilevel inheritance...
