Apache JSPWiki is a free, open-source wiki engine written in Java and JSP.
What Apache JSPWiki is
Apache JSPWiki is a free, open-source wiki engine written in Java and JSP. It supports JSPWiki syntax and Markdown, with the option to plug in additional syntax implementations. Pages are plain text files by default, and administrators can select page storage and search providers. The engine supports file attachments, templates for custom themes or layouts, page comments, multiple wikis and page locking to prevent editing conflicts. Access controls include wiki-level and page-level privileges, user and group controls, and XML, database, container-managed or custom authentication. Plugin and page-filter interfaces allow added functionality and page processing. JSPWiki can run as a WAR on a servlet container such as Tomcat, in Docker or through portable binaries. Setup requires JDK 11 or higher and a JSP engine supporting Servlet API 3.1; Tomcat 9 or later is recommended. Security guidance recommends TLS, reviewed configuration, updated Java and servlet software, and limits on access and uploads. Attachments have no built-in total count or size cap, so disk usage needs monitoring.
