Не удалось инициализировать Atmosphere Framework на vaadin 14
Я добавил поток Vaadin 14 в существующее приложение JavaEE 8, которое имеет реализации Perimeface 6.2 на интерфейсе с использованием Wildfly 18 в качестве контейнера сервера. Приложение работает нормально, но перед развертыванием я получаю следующую ошибку. Я искал в Интернете, но не мог понять, почему это происходит.
Я знаю, что это связано с Java API для WebSocket, и сервлет Vaadin пробовал следующее.
Добавлена зависимость от pom.
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>flow-push</artifactId>
</dependency>
Добавлено @push к основному классу Ваадин.
import com.vaadin.flow.component.page.Push;
Кто-нибудь знает в чем причина и как решить?
Конфигурация сервлета Vaadin:
<servlet>
<servlet-name>Vaadin Servlet</servlet-name>
<servlet-class>com.vaadin.flow.server.VaadinServlet</servlet-class>
<init-param>
<param-name>i18n.provider</param-name>
<param-value>translation.TranslationProvider</param-value>
</init-param>
</servlet>
ошибка, как показано ниже:

Добавление следующего в сервлет устранило проблему. Надеюсь, это сэкономит время и силы:)
