Forum Web Application with feature set superior to phpBB

pushedAt 11 months ago



This forum was created due to a number of pressing problems we saw in available open-source Java based (Servlet/JSP) Forum Engines.

  • Using the database for everything, including searching and indexing
  • No free forum that allows sub-forums to any depth
  • No free ones having all the capabilities we wanted in one package, especially:

We directly leverage a bunch of open-source products:


This repository is part of a multi-project gradle build.

It has the following dependencies:

Before building:

  • clone the dependencies into adjacent folders directly under same parent folder
  • download settings.gradle into the parent folder


gradle clean
gradle build


gradle appRunWar


To start, you must have access to a database.

You can have your admin create a database instance using the commands below:

CREATE USER 'collab'@'localhost' IDENTIFIED BY 'pw4collab';
GRANT ALL ON collab.* TO 'collab'@'localhost';

Thereafter, you can login to use it locally using

/usr/local/mysql/bin/mysql -u collab -ppw4collab collab

Once in, you can do the following:

source src/main/resources/net.ugorji.oxygen/forum/database/mysql.sql

Usage Information

The user manual is available at src/main/resources/net.ugorji.oxygen/forum/help.txt. We store it there since it has to be loaded up by the forum engine to show bundled help.

Locale Management

In the forum, there is only one big sandbox. Consequently, a locale must only be set administratively, and applies to the whole forum. The locale set is the same one which is used as the language for creating topics and posts.
