tomcat deploy module war to sub url path

I have a multi-module maven project whose structure looks like this:

app                // parent/root project folder
 |- src         
 |- target
      |- app.war   // common features
 |- app-payment    // child/module folder
        |- src   
        |- target
             |- app-payment.war  // shop/pay features

How can I map the two war files to urls like below? 

requests for    
   localhost:8080/app/payment   --goto-->   $CATALINA_HOME/webapps/app-payment.war (or any other locations, doesn't matter)
other requests for
   localhost:8080/app           --goto-->   $CATALINA_HOME/webapps/app.war

The web.xml -> <servlet-mapping> both are <url-pattern>/</url-pattern>.

I'm using tomcat 8.5 and want to keep default settings if possible (e.g., do not add <Context> in server.xml, leave autoDeploy=true). So probably the approaches provided in A word on Contexts at https://tomcat.apache.org/tomcat-8.5-doc/deployer-howto.html would not work (have tried anyway and no).

In case this turns out to be an XY problem...Is it the right way to use/modify tomcat to achieve such url pattern? Or should I change the project settings (or design)? It's a spring-mvc project and the whole spring-*.xml thing is like a myth...

Try changing context.xml of your war file

 <Context antiJARLocking="true" path="/app/payment"/>

By default, it would be 

 <Context antiJARLocking="true" path="/app-payment"/>

I know this is an old post, but thought I'd share. I had to do something similar where I have a web application, then another separate web application that needed to run under the core app's same directory name. So something like...

https://www.example.com/webapp (main app)
https://www.example.com/webapp/subapp (sub-app)

To do this, I deployed it to the Tomcat webapps folder like this:

../webapps/webapp.war
../webapps/webapp#subapp.war

Worked like a charm for me. If I remember correctly, this is fully supported without any other configuration (both Tomcat v7 and v8... haven't tried v9 yet).
