NewsForge | Lucane: Simple open source groupware
Need groupware that doesn’t require tedious installation and configuration, and is ready for use in a matter of minutes? Lucane can be deployed in no time, and is so simple to use that you don’t need to spend hours learning it. Lucane has a modular architecture and includes an impressive range of pre-made modules, including a multi-user calendar, an email client, instant messaging, a white board, forums, notes, shared folders, and an RSS reader. Users can easily add and remove modules to customise their groupware environment, and developers can create additional modules and plug them in Lucane.
Unlike many other groupware applications, Lucane does not require the PHP/MySQL combination. It is written entirely in Java, and comes with all the necessary components. This means you can deploy Lucane on Windows, Linux, or Mac OS X without installing additional software. Lucane relies on a database back end, and by default it uses the supplied and preconfigured HSQLDB engine. However, the application also supports MySQL, PostgreSQL, and Microsoft SQL Server.
