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.
jminix is a simple embeddable restful JMX console. It is useful for when you don't want to use an external full-blown JMX console, but just want to have a simple JMX entry point into your new or existing apps. Embedding JMiniX in a Web app is done simply by declaring a servlet. Deployed as a servlet, it benefits from your Web application configuration such as filters or security constraints.
