WSO2 BAM REST-API Пример выполнения

Question

У меня есть WSO2BAM V2.2.0, установленный в Windows 7 и Cygwin 1.7.18. Когда я пытаюсь запустить образец REST-API, я получаю следующую ошибку в консоли BAM.
Может кто-нибудь, пожалуйста, дайте мне знать, что может быть неправильным и как решить проблему?

Answer 1

Я не уверен, но вижу ли ваша версия Java JDK 1.7. Если это так, перейдите на JDK 1.6.

Answer 2

Эта проблема не должна быть связана с проблемой Cygwin или при публикации данных в BAM через API останова. Кажется, эта проблема возникла при параллельном запуске нескольких сценариев улья. Сколько наборов инструментов вы установили, когда получите эту проблему?

Answer 3

Попробуйте настроить в Linux, это может сработать.
