When the client accesses a non-existent resource, and a servlet in which an exception occurred, the Web container returns an error status code. An error page corresponding to the error status code returned from the Web container is displayed in the client. In an application server, instead of the error pages displayed in the client, pages created by the user can be displayed in the client. This is called error page customization.

This section describes the customization of the error page with the Web server functionality when the system is integrated with the Web server.

The following table describes the organization of this section.
