I'm trying to deploy a React app in Jenkins using Tomcat 9. Everything is working except when I try to enter an invalid route in the browser's address bar. It only displays the Tomcat 404 page instead of my custom 404 page.

The solution I found in the documentation led me to this answer. Now, the problem is how can I dynamically add a web.xml file inside the war file that gets built and deployed in Jenkins? I have tried adding it inside my project's public folder, but it only gets added inside the build folder.

It turns out, the web.xml file is indeed getting added inside the war file when I put it inside the public folder but routes are still not working.

I tried deploying my React app using the Maven project instead of a Freestyle project and found out that the web.xml file is inside the WEB-INF folder.

I just had to create that folder inside public and add my web.xml in there.
