Welcome to Apache Wicket

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.

Wicket is released under the Apache License, Version 2.0.

Apache Wicket 7.0.0-M4 released

The Apache Wicket PMC is proud to announce Apache Wicket 7.0.0-M4!

We have released another milestone release for Apache Wicket 7. We aim to finalise Wicket 7 over the coming months and request your help in testing the new major version.

Caveats

It is still a development version so expect API breaks to happen over the course of the coming milestone releases.

Semantic versioning

As we adopted semver Wicket 7 will be the first release since 6.0 where we are able to refactor the API. We will continue to use semver when we have made Wicket 7 final and maintain api compatibility between minor versions of Wicket 7.

Requirements

Wicket 7 requires the following:

  • Java 7
  • Servlet 3 compatible container

You can’t mix wicket libraries from prior Wicket versions with Wicket 7.

Migration guide

As usual we have a migration guide available online for people migrating their applications to Wicket 7. We will continue to update the guide as development progresses. If you find something that is not in the guide, please update the guide, or let us know so we can update the guide.

You can find the guide here: http://s.apache.org/wicket7migrate

Using this release

With Apache Maven update your dependency to (and don’t forget to update any other dependencies on Wicket projects to the same version):

<dependency>
    <groupId>org.apache.wicket</groupId>
    <artifactId>wicket-core</artifactId>
    <version>7.0.0-M4</version>
</dependency>

Or download and build the distribution yourself, or use our convenience binary package
