-1

Я пытаюсь запустить простое приложение двигатель гостевого приложения модифицированное для Spring Я бег спосо InteliJ IDEAjavax/сервлет/ServletContext: неподдерживаемый MAJOR.MINOR версия 52,0

Поскольку AppEngine, мне нужно работать на JAVA 7 Когда я компилирую компилятор Java 8, у меня нет проблем. Однако при компиляции с Java 7, я получаю это:

Мой JAVA_HOME является Исеть в Java7, внутри структуры проекта Project SDK определена для Java7. JDK для импортера maven - Java77, JRE для maven runner установлен в Project JDK

Не могли бы вы рассказать мне, как возможно, что я получаю эту ошибку, даже если у меня есть все настроенное для Java 7? А также, как это исправить :)

Благодарности

Servlet 4.0 основан на Java 8. Если вам нужно для запуска на Java 7, вы не должны использовать эту версию API сервлета, которая скомпилирована с Java 8. –

глупого меня ... решения было использовать javax.servlet-апите версии 3.1.0
