Tomcat resides in a location like 'C:\Program Files (x86)\CA\SC\Tomcat\8.0.26', but where the Tomcat Error Handling page can be configured?
When a user enters an invalid URL it would redirect them to a 404 error handling page. This location may need to be changed to address a potential security vulnerability or just to provide a custom page instead of the default.
Client Automation all supported versions
What you really want is to know where you can specify a custom 404.html landing page.
To do that you need to edit the <error-page> section of 'Web.xml' with text like the following:
<error-page>
<error-code>404</error-code>
<location>/path/to/your/page.html</location>
</error-page>
