J2EE: custom error page

If a custom error page for a specific HTTP error is needed:

1. Add the error page configuration in the web application's WEB-INF/web.xml:

2. Create a error404.html at the web application's root directory.

If such configuration is not set in the web application but somehow the 404 error can still trigger a custom error page, that may be because the administrator has done it for you in the Tomcat's conf/web.xml.
