Answer 1

1. Download the Java driver for your database. It is a .jar file such as mysql-connector-java-5.1.42-bin.jar for instance. It can be found on your database vendor's website.
2. Put that JAR file in the Tomcat of your Liferay server, in the lib/ext directory. Example: liferay-workspace/bundles/tomcat-8.0.32/lib/ext/mysql-connector-java-5.1.42-bin.jar
3. Restart Liferay.
