By default, drivers are not packaged with the iWay Hierarchy Manager plugin. Drivers are required for database connectivity tasks (for example, run-time data retrieval and publishing). You can add drivers to your Java Runtime Environment during the startup of Eclipse. To add drivers, modify the Eclipse.ini file located in the Eclipse root folder and specify driver paths under the -vmargs line using the following format:

-Xbootclasspath/a:PATH1;PATH2;PATH3

For example:

-Xbootclasspath/a:D:\Drivers\mysql-connector-java-
5.1.21.jar;D:\Drivers\ojdbc6.jar;D:\Drivers\sqljdbc4.jar

Note: On non-Windows systems, semicolon characters (;) should be replaced with colon characters (:).
