  • Course Wicket Programming : Content

    The course Wicket Programming focuses on developing Java Web applications using the Wicket Framework. Wicket is an open source, component oriented, server side, Java web application framework. In Wicket Web Applications are developed using only Java code and HTML files with wicket markup tags. The latest version of Wicket is based on Java 11 and supports new Java technologies such as Java modularization and new libraries such as JUnit 5.

    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.


    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.


    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.

    Course Forms

    All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.


    We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.

    Course times

    The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.


    We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.


    Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.


    The course includes lunch that we use in a restaurant within walking distance of the course room.


    The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.


    At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.


    The intellectual property rights of the published course content, also referred to as an information sheet, belong to SpiralTrain. It is not allowed to publish the course information, the information sheet, in written or digital form without the explicit permission of SpiralTrain. The course content is to be understood as the description of the course content in sentences as well as the division of the course into modules and topics in the modules.
