If you like to create a new data source, you have to choose a driver first. Differently to all other data source properties, the driver can not be changed at a later point in time. In this dialog you'll see a list of currently available drivers. A driver is available if its *.jar file is in the Java classpath and the driver is known (preconfigured).
User-defined driver: | This enables you to add non-preconfigured drivers. |
Scan in classpath: | Scans the classpath for pre-defined drivers. |
