Примечание: Jetty 9.0.x является переходным re аренду для сервлета 3.1 spec (он использует черновик/бета-версии Servlet 3.1 api). Рассмотрите хотя бы обновление до Jetty 9.2.x (или Jetty 9.3.x, если вы уже на Java 8) –

Ваша переменная contextpath не определена:

<contextPath />

вам нужно изменить его на что-то значимое, как:

<contextPath>/</contextPath>

Это сопоставит веб-приложение в корневой контекст, так что вы можете доступ к нему:

http://host:port/
