ObjectDataSourceFinder
public final class DataSourceFinder
Enable programs to find all available DataSourceFactorySpi
implementations.
In addition to implementing this interface data souces should have a services file:META-INF/services/org.geotools.data.jdbc.DataSourceFactorySpi
The file should contain a single line which gives the full name of the implementing class.
Example:org.geotools.data.jdbc.DBCPDataSourceFactory
