Подключение Java к Firebird

0 голосов
/ 05 июня 2018

У меня есть проект Maven, и я сгенерировал .war из этого проекта.Я установил tomcat 32-битный / 64-битный Windows Service Installer для развертывания.Когда я пытаюсь сделать все заявки, которым нужен доступ к базе данных, я получаю ошибку 500 Internal Server Error.Я думаю, что проблема в persistence.xml, но я не знаю, что именно.

  • Java 8
  • Tomcat 8.5
  • Firebird 3.0.3
