Apache JSPWiki is an open source Java wiki engine: write and link pages with simple markup, attach files, and keep the full version history of every page.
Apache JSPWiki is a feature rich, open source wiki engine built on standard Java servlet technology. Authors create and link pages using a compact wiki markup, attach files to any page, and rely on built in versioning so every change is tracked and any earlier revision can be restored. A plugin and filter system extends the engine with tables of contents, recent changes lists, full text search and custom macros, while a fine grained access policy governs who may read, edit and manage each page.
It suits teams that want a self hosted knowledge base or documentation site they fully control: engineering and IT groups documenting systems and runbooks, project teams keeping shared notes and specifications, and organisations that need an internal reference wiki with page history and real access control rather than a hosted service.
Running JSPWiki yourself means installing a servlet container and a Java runtime, deploying and configuring the wiki application, wiring up its page store and user database, and hardening a default install that ships wide open to anonymous editing. cloudimg ships that whole stack assembled and proven, and it boots into a real, rendered wiki with a starter set of pages rather than a blank first run screen. Security is designed in: the administrator password is generated uniquely on first boot and is never shipped as a default, and the access policy is locked down to public read, administrator write, so a public facing wiki is not an open target for spam the moment it launches. A written deploy guide walks you through launch, first sign in and how to open editing up to your team, and every image is backed by 24/7 support.
