Yes, but there are a number of edge cases in all the above. The Tomcat 8 docs cover this in a lot more detail: http://tomcat.apache.org/tomcat-8.0-doc/config/automatic-deployment.html I think there are a few cases where Tomcat 7 is not quite consistent with this (back-porting the docs and the associated changes are on my TODO list). In most cases, Tomcat 7 should be consistent with this. > By my slightly addled understanding of the Configuration Reference, the > deployOnStartup flag also lives there, and defaults to true; yet I don't > see it there.

This is why if you update a WAR while Tomcat is shut down and do not delete the associated expanded directory (which is the expanded old version) when Tomcat restarts Tomcat assumes the directory is the result of expanding the WAR and deploys the directory.
