Custom error page
When a user requests a non-existing page, the servlet container (Tomcat) or application server displays a 404
error page and returns the 404
error code. You can configure what happens in the case of a 404
directly in the web.xml
configuration file in the container.
A common solution is to create a custom error page that looks like the rest of your site, tells the visitor in clear terms that the page was not found, and provides some alternative ways to continue such as navigation and a search box.
<error-page>
<error-code>404</error-code>
<location>/error/404.html</location>
</error-page>
404
is, of course, not the only error code. You can set up custom error pages for any error code using the same approach.
