You should set up the connection to the database in context.xml (configuration file tomcat7) the example below.

You should copy the files: "mysql-connector-java-5.1.38-bin.jar", "mysql-connector-java-3.1.8-bin.jar" to the directory "./tomcat7/lib"

The example of configuration file context.xml:

</Context>

It should works.

In above configuration software required server installed MySql database "scadalts" and the root user with the password root on localhost.
