Развертывание EJB 2.1 в выпуске weblogic 12c

Question

Я пытаюсь развернуть EJB 2.1, обернутый в приложении EAR maven, в weblogic 12c, я упомянул, что предпочитаю ejb 2.1 jar в моем classpath, но все же я получаю приведенную ниже ошибку, поскольку она ссылается на weblogic ejb jar.

Я пробую разные вещи, но все же это не мое. Пожалуйста, найдите ниже XML-файлы и не могли бы вы помочь мне в решении этой проблемы?

Мне надоело искать причину:(

There are 6 nested errors:
