-

in tomcat config have docbase this:

<context path="/" docbase="webapps/rootexample"/>

is possible provide docbase property @ runtime @ tomcat startup external properties file or -d system property?

what provide <context-param> in web.xml similar thing.

another alternative use jndi each webapp has sort of mechanism of checking configuration setting in there.
