How to configure custom error page for 400 error

[mahesh-tier1app]

When I access malformed URIs in my application, the server redirects to Tomcat's default 400 error page, as shown below:

I want to display a custom error page instead of the default one. To achieve this, I configured the ErrorReportValve using the following attributes:

-AclassName="org.apache.catalina.valves.ErrorReportValve" -AerrorCode.400="webapps/expanded/400-custom-error.html" -AshowReport=false -AshowServerInfo=false

Despite this configuration, the custom error page does not appear. The default Tomcat error page is still displayed.

Could you please confirm if this is the correct approach or let me know if I am missing any steps?

Environment Details:

OS: Windows
Java Version: JDK17
Webapp-runner Version: 9.0.97

I found a workaround to hide all information on the 400 error page except the header. To hide we can pass the --secure-error-report-valve flag to the webapp-runner.jar
