You can create customize error and exception reports that are sent to clients. When the servlet engine detects an error or catches an exception thrown by a servlet, it searches for a corresponding error page to handle the response. You can declare error pages for a Web application, or at the server level.
This example illustrates how to declare an error page for a Web application in the deployment descriptor:
<error-page> <error-code>404</error-code> <location>/etc/404.html</location> </error-page>
The location is the path relative to the Web application’s context root. For example, /etc/404.html corresponds to this file in your EAServer installation directory, where web-app is the name of the Web application:
deploy/webapps/web-app/etc/404.html
