If you want Tapestry to render your error page, you need to configure
the filter to handle error dispatches:
<filter-mapping>
<filter-name>app</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
Entirely possible that Jetty would route this to the app by default
but I think it's off-spec.
