Active development of JAMWiki has ceased, and bug fixes and support will be limited at best. If you are interested in taking over management of JAMWiki please send an email to the jamwiki-devel mailing list.


JAMWiki is a Java-based wiki engine that offers many of the features of MediaWiki. Setup is quick and easy with no external database required. The code can be run on almost any application server running Java 5 or greater and is licensed under the GNU Lesser General Public License (LGPL).
