Исключение из JAX-RS с RESTEASY с TOMCAT 7

Question

Я пытаюсь реализовать RESTFULL-сервис с RESTEASY. Когда я пытаюсь запустить Tomcat Server 7.0, я получаю исключение. Подробнее см. Ниже.

Может кто-то пожалуйста, помогите по этому поводу?

Значение аннотации @Path является строкой, чувствительной к регистру. В коде службы, HelloService помечается @Path("/HelloResteasy"), но ваш путь запроса http://localhost:8080/RestEasyHello/service/HelloRestEasy/response/

@ApplicationPath определяет относительный базовый URL-путь для всех сервисов JAX-RS в развертывании. Таким образом, в вашем коде все JAX-RS RESTful-сервисы должны быть префиксны с помощью пути /services при выполнении. То есть, http://localhost:8080/service/HelloRestEasy/response/
