GWiki is an embeddable Wiki engine. It allows users to edit rich text fragments in an application you develop. It supports I18N files and mulitimedia content. Gwiki can be extended with macros written in Java or Groovy. It has a powerful right and role system, which can be fed from external sources such as LDAP, and allows access to business entitiels from wiki pages. It comes with Wicket integration out-of-the-box. Wicket-HTML-Fragments can be held within GWiki, so these pages can be managed by the Wiki System, while Wicket handles the application logic. GWiki can be deployed as a servlet on every servlet container. GWiki can use a filesystem, a Zip archive, or a database for its content storage.
visural-wicket is a useful set of light-weight, loosely coupled components and utilities for the Apache Wicket Web framework. Each component is designed to be easily integrated into any existing Wicket application with minimal dependencies. Each component is also designed to be easily customized to fit a particular system's requirements. Other than components, visural-wicket includes some other utilities that assist in the development of Wicket applications, such as an annotation-based mounting system, model templates, and an automatic "form view mode" component.
