Я пытаюсь использовать случай, когда фактический XML должен быть преобразован в Java Объект с помощью xml -to-object-transformer> transformer в Mule3., Без DW. У меня возникла странная проблема, и, если кто-то может помочь, пожалуйста, просим:
. Для этого
- Сгенерировал класс JAXB, используя XJ C JAXB API
- Выполните xml -объект-преобразователь с указанным выше псевдонимом
