Okay, that's an interesting idea if it's possible to agree on a sane set :) Thanks for your feedback! Another option (I think) is to use the property replacement feature. I.e. ${property.name} in web.xml and property.name=foo in catalina.properties The only question is if this works in web.xml which I don't recall and I don't have easy access to the source to check. If it doesn't work we should be able to fix that easily. +1. I am sure that it works in web.xml. Also things to note: 1) It is recommended to configure an IP filter (RemoteAddrValve) for manager web application in its context file. http://tomcat.apache.org/tomcat-8.0-doc/security-howto.html#Securing_Management_Applications 2) It should be possible to shadow (override) WEB-INF/web.xml of an application by configuring a PreResources element in its context file, http://tomcat.apache.org/tomcat-8.0-doc/config/resources.html 3) You can rename the application, configure it, pack into a war and upload via the default manager app. The name of the manager application does not matter. It can be renamed. (If you are running with java SecurityManager enabled, it will require additional configuration in policy file, and to configure context file for the application).
