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.

You can find out more about Apache Wicket on our website:
