Apache JSPWiki

Apache JSPWiki can be used as an alternative to Wikipedia's free engine, MediaWiki, a cumbersome solution that sometimes takes up just too much space on the server.

All the classic wiki features are there, from real-time page editing, to page histories, and a changes tracker for reversing bad edits.

By default the wiki saves all content to plain text files, but other databases like MySQL can be used via plugins.

You can also follow edits via RSS, allow users to edit it only if logged in, and even control editing privileges using a fine-grained permissions system.
