Apache Wicket is an open source, java, component based, web application framework. With proper mark-up/logic separation, a POJO data model, and a refreshing lack of XML, Apache Wicket makes developing web-apps simple and enjoyable again. Swap the boilerplate, complex debugging and brittle code for powerful, reusable components written with plain Java and HTML.
Apache Wicket can be found at https://wicket.apache.org and is licensed under the Apache Software Foundation license, version 2.0.
The Wicket project has several resources and projects where you can learn from, and get started quickly:
The Wicket user guide - https://wicket.apache.org/learn/#guide:
learn Wicket from scratch reading its user guide which gradually introduces you to the various features of the framework with many real-world examples.
The Wicket JavaDoc:
the API Docs are available on the main site of the project: https://wicket.apache.org/learn/#javadoc
shows all components in short usage examples, also available live on: https://examples9x.wicket.apache.org
Wicket Quickstart - https://wicket.apache.org/start/quickstart.html:
provides a skeleton project for use in NetBeans, Eclipse, IntelliJ IDEA and other major IDE‘s, without having to configure anything yourself. Just copy’n'paste the generated command line and Maven will do the job.
You can download Wicket's source package here: https://wicket.apache.org/start/wicket-9.x.html . It contains the source code and the jars of the core projects of Wicket. If you are just starting out, you probably only need to include wicket-util-x.jar, wicket-request-x.jar and wicket-core-x.jar, where x stands for the version. As a rule, use just the jars you need.
You will find the source code here:

Here is a list of projects in the distribution and what they do.
The easiest way of getting the dependencies of your Wicket based projects right is to use Apache Maven (https://maven.apache.org) with your projects and include the wicket dependencies you want as outlined in the wicket-quickstart. Maven will then take care of including the appropriate dependencies.
If you do not want to use Maven, here is a break-down of the dependencies you need. For the complete and precise reference see the wicket-parent pom.xml in the root folder.
wicket and wicket-extensions:
You only need to include the Servlet API (3.1, just for compiling), SLF4J API and the SLF4J logging implementation you want. You cannot use Wicket without adding a SLF4J logging implementation to your classpath. Please see the SLF4J site (https://www.slf4j.org/) for more information.
As the following projects all depend on Wicket, they inherit these dependencies.
Apache Velocity 1.7 (https://velocity.apache.org/) and it's dependencies (it ships a velocity-deps jar for convenience)
wicket-ioc and Spring (https://spring.io/projects/spring-framework/) and it's dependencies
Google Guice (https://github.com/google/guice)
wicket-cdi: Component Dependency Injection 2.0 (https://cdi-spec.org/)
All of the above.
Wicket's source distribution (download package mentioned above) contains also the binaries (jar files) for each of its modules (subprojects). You can use these directly in your applications. The Wicket project uploads the source and JavaDoc jars to the Maven repository used by the Maven build tool as well. So there is actually no specific need to build Wicket yourself from the distribution.
When building using Maven 2 or 3, execute one of the following in the root folder:
creates wicket-(subproject)-x.y.z.jar(s) in according target subdirectories.
creates wicket-(subproject)-x.y.z.jar(s) in according target subdirectories and installs the jar files into your local Maven repository for use in other projects.

For encoding HTTP URL data (see org.apache.wicket.core.request.mapper.CryptoMapper) Wicket requires the Java Cryptography extensions (http://java.sun.com/javase/technologies/security/). Wicket does not include these libraries itself, but is designed to use them.
