JForum2
Bug fixes and enhancements for JForum 2.x
JForum is a powerful and robust discussion board system implemented in Java. It provides an attractive interface, an efficient forum engine, an easy to use administrative panel, an advanced permission control system and much more. Built from the ground up around an MVC framework , it can be deployed on any Servlet 3.1 container or application server running at least Java 8, such as Tomcat, Jetty and JBoss/WildFly. Its clean design and implementation make JForum easy to customize and extend.
There is extensive documentation of all aspects of the software at https://sourceforge.net/p/jforum2/wiki2/Home/
Source code and a beta build are available for running JForum on JakartaEE 10 environments such as Tomcat 10.1; it requires Java 11. This has not been tested as extensively, and remains work in progress.
It is freely available under the BSD license, and has recently been awarded the SourceForge "Community Choice" badge.
