,RuntimeServicesAware
public class IncludeNotFound extends java.lang.Object implements IncludeEventHandler, RuntimeServicesAware, ContextAware
Simple event handler that checks to see if an included page is available. If not, it includes a designated replacement page instead.By default, the name of the replacement page is "notfound.vm", however this page name can be changed by setting the Velocity property
eventhandler.include.notfound
, for example:eventhandler.include.notfound = error.vm
The name of the missing resource is put into the Velocity context, under the key "missingResource", so that the "notfound" template can report the missing resource with a Velocity reference, like:
$missingResource
