You want "context aliases":

plementation

Search for the "aliases" attribute.

You want "post-load resources":

https://tomcat.apache.org/tomcat-8.5-doc/config/resources.html

Search for "PostResources".

Resources are available in both pre-resource and post-resource forms.
I recommend using post-resource so that a stray file in the target
location can't mask a file provided by the application.

On the other hand, if the application contains a "default config file"
and you want to override it with an environment-specific replacement,
then you'll want to use pre-resources instead of post-resources.

Note that "resources" are used to load EVERYTHING, including class
files, etc. You should read and re-read the entire section on
Resources in the user-guide until you understand the implications of
the configuration you are about to implement.
