Ошибка при запуске сервера WildFly - Unable to get managed connection

Ошибка при запуске сервера WildFly (JBoss). Как я понял, он ругается на отсутствие dsArc. Дело в том, что этот модуль есть в другом схожем проекте, но как его правильно подключить? Достаточно ли будет перенести только готовый .jar файл с другого проекта как библиотеку? Я только начал работать и не особо разбираюсь в этом, поэтому желательно "на пальцах".
