Thank you for downloading Confluence 2.10.4 - Standalone distribution. This distribution comes with a built-in Tomcat 6.0.14 web server and hsql database, so it runs (almost) out the box.
A common startup problem is when another program has claimed port 8080, which Confluence is configured to run on by default. To avoid this port conflict, Confluence's port can be changed in conf/server.xml.
If you encounter any errors, please visit our online documentation at http://confluence.atlassian.com/x/8hIC or open a support case at our support JIRA instance.
Thank you for using Confluence!
