Я создал гаджет с инструментом гаджета, подключающимся к моей локальной базе данных postgresql ... Все работало отлично, но когда я добавляю гаджет в свою панель управления гаджетом, он ничего не показывает.
Это мой гаджет маршрут:Инструмент гаджета BAM

/registry/resource/_system/config/repository/components/org.wso2.carbon.bam.gadgetgen/gadgetgen/tabla.xml

Это ошибка консоли:

Caused by: org.jaggeryjs.scriptengine.exceptions.ScriptException: Error connecting to the database : jdbc:postgresql://127.0.0.1:5432/wso2bam_postgresql 

btw, i have read all the related documentation without success

ли вы включили .jar драйвера к $ BAM_HOME/хранилище/компоненты/Библиотека каталога? И могли ли вы видеть данные в предварительном просмотре, когда вы создаете гаджет в мастере gadget-gen?

Убедитесь, что выше двух, и укажите всю трассировку стека, а не только сообщение об ошибке.

hello, yep У меня есть драйвер, расположенный в соответствующей директории ... и да, я могу просмотреть таблицу/бар ... btw, что вы называете «весь стек» полным log после запуска .sh-скрипта? ... я очень нуб для BAM, я прочитал документацию, и я пытаюсь извлечь данные из базы данных для создания простого KPI ... спасибо заранее – Carlos

Ошибка stacktrace означает всю следность. Вы включили только первую строку stacktrace. Включите всю трассировку исключений. – Ragavan

Здравствуйте @Ragavan, прошу прощения за задержку, я обновил вопрос журналом. Спасибо – Carlos

В файле jag, созданном для гаджета в // репозитории/развертывании/сервере/jaggeryapps/gadgetgen, будет переменная 'config' с пустым {}. Измените его на

var config = {"driverClassName":"org.postgresql.Driver"};
