Проблема при развертывании приложения на основе рестлета на tomcat

Question

Проблема при развертывании приложения на основе рестлета на tomcat

У меня проблема с развертыванием приложения рестлета на веб-сервере tomcat.

Я могу запустить приложение напрямую из Eclipse, но при развертывании на tomcat у меня возникают следующие проблемы.

Я проверил, и файл simple.jar является частью развернутой войны.

Может кто-нибудь подсказать, что это за незаконный доступ и как я могу его решить.

Благодарю.

Я предполагаю, что вы смешали автономный и встроенный подход Restlet:

При автономном подходе вам нужен серверный соединитель, такой как Simple framework или Jetty, и Restlet отвечает за их управление (запуск, остановка)
Благодаря встроенному подходу Restlet больше не нужно управлять этим. Вы запускаете свой механизм сервлетов, и запросы будут переданы в Restlet через его сервлет-адаптер.

Делаете ли вы попытку в Eclipse, используя автономный или встроенный подход (например, с WTP)?

Вот файл Maven, который позволяет вам создать встроенный проект:

Инициализация проекта для Eclipse может быть выполнена с помощью команды mvn eclipse:eclipse,
