Я использую FTP-сервер Apache. FTP-сервер загружается через singleton bean-компонент в Glassfish. Раньше я мог запускать FTP-сервер, когда использовал PropertiesUserManager, но я хотел связать некоторую логику JPA, поэтому я написал собственный класс класса, который реализует интерфейс UserManager. Однако я столкнулся с проблемой загрузки класса. Файл slf4j-api-1.6.1.jar и файл slf4j-jdk14-1.6.1.jar существуют в папке lib Glassfish, и я перезапустил Glassfish.
Вот трассировка стека:
