ClassNotFoundException: javax.сервлет.AsyncContext в Jetty hello world в eclipse

Я прошел по ссылке http://wiki.eclipse.org/Jetty/Tutorial/Jetty_HelloWorld учебник (с Eclipse). а также посмотрел на существующий stackoverflow здесь

Я использую агрегатную пристань 8.0.0.jar и 8.1.3.jar вместе с сервлетом-api-2.5.кувшин. Я добавил Эти 2 банки в путь к классу, а также включил slf4j-simple-1.6.4.и Джар тоже.

Я все еще получаю
