Som,
Without a web.xml, the Jersey servlet is not setup to handle requests.
Without Jersey, there is nothing in Jetty to map any request to MyResource.
Unless there is something annotated or in a discovered webfragment, then
Jetty has no handler for that request and 404 is the correct response.
regards
