Мой веб-сервис не возвращает правильный ответ для SOAP из-за исключения ленивой инициализации

У меня есть работающая веб-служба, и я могу прочитать свой wsdl по правильному URL-адресу. У меня также есть служба, модель и потребитель, которые работают, потому что, когда я отправляю запрос в режиме отладки, я вижу результат из своей БД. Но когда мой WebMethod возвращает результат, у меня просто пустой ответ и ошибка в журнале Glassfish, в котором говорится: не удалось лениво инициализировать набор ролей: p3.model.book.Book.borrowing, не удалось инициализировать прокси - нет сеанса

Я думал, что это была ленивая загрузка моего заимствования, но, похоже, это не так.

в моем режиме отладки у меня есть эта проблема, и я не знаю, как ее решить:

отлаживать до возврата ответа

У кого-нибудь есть идея?

Спасибо, что прочитали и помогли мне.
