UnsupportedOperationException - Приложение должно предоставить соединения JDBC

при запуске моего спящего/весеннего приложения я получаю следующее исключение:

Однако при просмотре в persistance.xml вы можете увидеть:

    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </properties>
    </persistence-unit>

</persistence>

Я предполагаю, что файл настроен правильно, для спящего режима и соединения hsql. С другой стороны, есть мое applicationContext.xml, которое выглядит следующим образом:

Мой вопрос: почему я получаю это исключение? Любые рекомендации, что неправильно настроено? Я лично считаю, что мой applicationContext.xml не прав, однако я не уверен, где ошибка.

Я ценю ваш ответ!
