Ошибка входа в спящий режим

Я использую hibernate для своего мобильного приложения и успешно подключаюсь к mysql db. Но в первом входе в db запрос http не выполнен. Я пробовал и искал везде, но не нашел ответа. Я понял, что после таймаута сервер и db перестанут подключаться, и поэтому первый запрос не удался. это мой hibernate.cfg.xml:Ошибка входа в спящий режим

EDIT: я добавил конфигурацию C3P0 в hibernate.cfg.xml, но я все еще получаю исключение на первое соединение:

Эй, спасибо за ответ. Я добавил c3p0 в hibernate.cfg.xml, но теперь я получаю эту ошибку: «Caused by: java.lang.ClassNotFoundException: org.hibernate.connection.ConnectionProvider" Что мне нужно делать? Я использую спящий режим 4.3.6. –
