Examples of org.geotools.data.DataSourceException

org.geotools.data.DataSourceException
Thrown when there is an error in a datasource.
This class was used back in Java 1.3 before the initCause() method was available for IOException. Since this class is used to pass on problems from external services, providing the root cause is important.
