Scada-Lts — ошибка «Не указан источник данных»

Я попытался запустить Scada-Lts на Tomcat 7 с jdk 1.7 и получил следующую ошибку:

SEVERE: Exception sending context initialized event to listener instance of class com.serotonin.mango.MangoContextListener

Вы должны настроить подключение к базе данных в context.xml (файл конфигурации tomcat7) в примере ниже.

Вы должны скопировать файлы: "mysql-connector-java-5.1.38-bin.jar", "mysql-connector-java-3.1.8-bin.jar" в каталог "./tomcat7/lib"

Пример конфигурационного файла context.xml:

Это должно работать.

В приведенной выше конфигурации программного обеспечения требуется сервер с установленной базой данных MySql «scadalts» и пользователь root с паролем root на локальном хосте.

Конфигурации могут изменяться и подстраиваться под собственную среду. - person Grzesiek; 08.10.2016
