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.
