John,
This is as easy as setting up a ROOT webapp (just a directory, not a war)
and defining a 404 page within the web.xml. For example:
JETTY_BASE
|_webapps
|_ROOT
|_WEB-INF
|_web.xml
Inside this web.xml, you define a simple webapp that, in this case, just
serves up an error page:
<?xml version="1.0" encoding="UTF-8"?>
> <web-app
> xmlns="http://java.sun.com/xml/ns/javaee";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
> http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd";
> metadata-complete="true"
> version="2.5">
> <display-name>Simple WebApp</display-name>
>
> <error-page>
> <error-code>404</error-code>
> <location>/error404.html</location>
> </error-page>
> </web-app>
This will set up a 404 page that is served when no a request is not matched
to a particular webapp/context. All requests to correctly mapped virtual
hosts will be handled by their designated webapp/context.
Best,
Chris
