The Wicket Team

Apache Wicket

Apache Wicket is a component oriented Java 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.

Our migration to a top level project is now completed and you can find our website and documentation here:

This release

This release is the second in a series of release candidates releases until we feel confident to finalize Wicket 1.3. This is called a release candidate because we strive for API freeze. This means only bug fixes will be done on the 1.3 release from now on.

But one "new" thing has sneaked into this release and that is a new design of the examples. This is done in association with the Google Highly Open Participation which Wicket is participating.
