Documentation for Confluence 2.5.4 - 2.5.8.
Documentation for [Confluence Cloud] and the latest Confluence Server is available too.

In order to run Confluence under Resin 3, you will need to use a special version of web.xml. This has been bundled in the main Confluence download as:

confluence/WEB-INF/web.resin3.xml

To enable it, simply remove the default confluence/WEB-INF/web.xml and then rename web.resin3.xml to web.xml. Now restart.
