Wicket Programming

In the course Wicket Programming from SpiralTrain the participants learn to develop Java Web applications using the open source, component oriented, server side, Wicket java web application framework.

Wicket Intro

The course starts with an explanation of the architecture of Wicket. Attention is paid to how applications in Wicket are built from components that consist of a Java class and an associated HTML file with the same name. A Wicket identifier provides the link between the class and the HTML file.

Core Concepts

Next a number of important concepts in Wicket are covered, such as the RequestCycle, the difference between stateful and stateless pages, Wicket models and the page rendering process.

Component Hierarchy

Also the Wicket component hierarchy is treated with MarkupContainers, Panels, Listviews and many other components. The course Wicket Programming also discusses the life cycle of components and how you can use behaviors.

Models

Then the role of models in Wicket is explained. Wicket models allow components to retrieve data when they need to be displayed on the screen. Models also convert or save user input when events occur.

Wicket Forms

Wicket Forms are also on the program of the course. In this context form layout, processing user input, data conversion and validation are discussed.

Ajax

And also the combination of Wicket and Ajax is treated. The many built-in Ajax components such as AjaxEditableLable, AutoCompleteTextField and AjaxLink are covered and Ajax Behaviors as well.

Advanced Topics

Finally the integration with jQuery and Tree and Wizard components is on the schedule and the migration from older Wicket versions to the latest version 9 is treated.

Audience Course Wicket Programming

The course Wicket Programming is aimed at companies and individuals who are using or planning to use Wicket and require a detailed understanding of the relevant technologies.

Prerequisites Course Wicket Programming

Professional programming experience in Java and knowledge of Java Web applications is required.

Realization Training Wicket Programming

The subject matter is treated on the basis of presentation slides. Demos are used to clarify the theory. Ample exercises are done during the course. The course material is in English. The course times are from 9.30 up and to 16.30.

Certification Wicket Programming

Participants receive an official certificate Wicket Programming after successful completion of the course.
