Since JSPWiki 2.6, a new administration interface has been added under /admin/Admin.jsp. This interface is based on AdminBeans, a particular kind of bean which is used by JSPWiki to generate a HTML interface.
The AdminBeans can also be JMX beans, which means that it is possible to control them from a regular management application. However, instead of just using a constructed HTML user interface, the AdminBeans may have full control over the HTML they emit.
