Я протестировал Apache Tomcat 9.0.14 на своей локальной машине с классами сервлетов и файлами html / jsp, и у него нет проблем с поиском любого из них.Однако теперь я попытался развернуть его на экземпляре Amazon Lightsail, скопировав туда полную папку Tomcat, и теперь он показывает только сообщение об ошибке 404 not found для всего.Использование bin / startup.sh ясно показывает, что переменная CATALINA_HOME установлена в правильном каталоге.Я понятия не имею, как мне переконфигурировать Tomcat (если требуется), чтобы он мог найти классы сервлетов.Обратите внимание, что я пытаюсь получить классы в папке webapps / ROOT.
