I am using Jetty server with embedded web app. However, whenever I hit any resource which is not present it serves a default page which shows a message "Powered by Jetty".
This page is being served from org.eclipse.jetty.server.handler.DefaultHandler.handle.
I want write a custom handler for this, however while trying to register custom Handler in jetty.xml file, I am getting syntax exception and server doesn't start anymore.
I was able to resolve this issue by doing some tweaks along with changes mentioned in Deactivate Jetty's default 404 error handler.
