java.lang.IllegalStateException: Не удается переслать после ответа на 404

Question

У меня есть Spring 4.0.1 Java Web Application, развернутое на Glassfish 4.0. Всякий раз, когда возникает ошибка 404, в журналах есть исключение. Страница ошибки отображается правильно (это простой, простой html). Несмотря на то, что приложение работает нормально, я хотел бы избавиться от этого исключения. Это исключение НЕ выбрасывается при запуске localy на tomcat.

Ошибка страницы конфигурации в web.xml:

<error-page> 
    <error-code>404</error-code> 
    <location>/pages/404.html</location> 
</error-page> 

<error-page> 
    <exception-type>java.lang.Throwable</exception-type> 
    <location>/pages/500.html</location> 
</error-page> 

Место указывает на HTML файлы ресурсов.

Полный стек:

Answer 1

Это исключение часто происходит всякий раз, когда вы пытаетесь сделать вперед или редирект после уже сделали один раз. Основываясь на моем опыте, у вас, вероятно, есть где-то в вашем коде инструкция if с переадресацией, а затем другая переадресация/перенаправление. Если это так, просто добавьте предложение else перед вторым перенаправлением. Если это не проблема, вы можете отправить еще какой-нибудь код?
