JSP ошибка компиляции в коте 8

Question

Раньше я использовал кот 7.0.30 и недавно я переехал кот 8.0.21

После этого, всякий раза, когда я пытаюсь получить доступ к моему приложению, он дает ошибку компиляции JSP, как показано ниже,

Тип возвращаемого несовместима с JspSourceDependent.getDependants()

и ниже ошибки также,

метод getJspApplicationContext (ServletContext) не определено для типа JspFactory

Я также использую GWT 2.7.0 и SmartGWT PRO 4.1

Можете ли вы предложить разрешение на это? Я просмотрел предложенные ссылки, но это не помогло. Обновленные распорки в 2.3.20

проводки полной StackTrace ниже с -verbose: класс VM аргументом,

Answer 1

Удалите GWT-dev.jar файл, если вы включаете его.

У меня была эта проблема в последнее время. Это, как правило, происходит, когда есть это противоречивая банка, который содержит определение JspFactory, как описано здесь-

The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

С GWT, проверьте, если вы в том числе GWT-dev.jar файла. Он также содержит определение для JSPFactory. Вот что вызвало проблему, когда у меня было это. Убери это. Вероятно, вам это не нужно во время выполнения и не нужно включать банку.
