Scada-Lts - «Нет DataSource указано» Ошибка

Question

Я попытался запустить Scada-LTS на Tomcat 7 с JDK 1.7 и я получил следующее сообщение об ошибке:

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

Answer 1

Вы должны настроить подключение к базе данных в context.xml (файл конфигурации tomcat7), приведенный 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 файла конфигурации context.xml:

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->

    <!-- Uncomment this to enable Comet connection tacking (provides events 
     on session expiration as well as webapp lifecycle) -->

</Context> 

Она должна работать корректно.

В приведенном выше конфигурационном программном обеспечении требуется установленная сервером база данных MySql «scadalts» и корень пользователя с паролем root на localhost.
