Ошибка отчета CrystalClear [219] [Диспетчер пула] Не удается загрузить указанный драйвер: null null

Question

Мы можем нормально запускать отчеты Crystal, когда Java-приложение запускается из Eclipse IDE.

Однако, когда оно уже развернуто, при запуске отчетов происходит следующее.

[CC,TRACE] Report Error [225] The DB connection to "jdbc:inetora:cs-v-oracx4sd1.champ.aero:1521:CX4SD111?logging=true" failed (see crystalclear.properties): [Pool Manager] Cannot load specified driver: null null.

Следующие jar существуют и присутствуют в classpath crystalclear-8.x.jar oranxo-3.12.jar

Кто-нибудь знаком с вышеуказанной ошибкой?

Cannot load specified driver: null null

Как насчет используемых переменныхотобразить нулевой нуль в ошибке?Я думаю, что даст нам некоторое представление о проблеме, но я понятия не имею.У нас не было этой ошибки из предыдущей версии нашего приложения.Все параметры были такими же, как и раньше.

Answer 1

Оказывается, ошибка пути к классу. Драйвер Oranxo загружен приложением, но не смог загрузить его в механизм отчетов.
