JSF управлял bean, вызывая java.io.NotSerializableException во время развертывания Tomcat

При развертывании моего webApplication на Tomcat 7 я получаю консольный вывод ниже. После перезапуска сервера два или три раза он работает без исключений.

Я использую JSF, Tomcat и RMI-соединение с частью бизнес-логики (что не имеет значения здесь?)

@EJB в управляемом @ViewScoped bean вызывает java.io.NotSerializableException - Здесь я читал о Сериализации. Но в этом случае было активировано сохранение состояния клиентской стороны, что не так в моем webApp (насколько мне сообщает мой web.xml). Итак, нужна ли сериализация моих видимых ManagedBeans или есть другой сбой?

Здесь мой вывод консоли запуска (Sry для этих немецких частей в нем):

Это касается другой проблемы, чем вопрос, который вы связали. По умолчанию, когда Tomcat завершает работу, он будет сериализовать HttpSession на диск, который затем будет перезагружен с диска при запуске, чтобы конечные пользователи могли просто продолжить сеанс браузера без потери данных сеанса.

В этом случае любой атрибут сеанса должен реализовывать Serializable. Состояние представления JSF по умолчанию хранится в сеансе, включая все соответствующие области видимости beans. Им также необходимо реализовать Serializable, чтобы выжить при завершении/перезагрузке Tomcat.

Технически вы можете просто игнорировать его. JSF в любом случае воссоздает охват сеанса/представления beans, если он еще не представлен. Тем не менее, конечный пользователь не сможет продолжать использовать одни и те же данные с охватом сеанса/представления. Эти исключения не будут возникать, если сеанс не содержит каких-либо несериализуемых объектов. Вот почему это "иногда" работает.

Если вы хотите полностью отключить сохранение сеанса, чтобы не беспокоиться об этих исключениях/предупреждениях, вам нужно добавить элемент <Manager> с атрибутом empty pathname элемент <Context> рассматриваемого webapp.

<Context ... >
    <Manager pathname="" />
</Context>

В основном это объясняет, что Tomcat вообще не использует диспетчер сеансов.
