Ошибка поиска JNDI для ресурса Тип: javax.sql.DataSource

Question

Ошибка в названии. Это очень странно, потому что я делал некоторые изменения в коде xhtml и его bean-компонентах, включал и выключал и снова включал сервер glassfish несколько раз, и внезапно появилась эта ошибка. Я не трогал web.xml или любой из этих типов файлов во время работы, только xhtml и его компоненты.

Сообщение об ошибке:
