All Implemented Interfaces:

java.io.Serializable

public class DataSourceException

extends java.lang.Exception

All exceptions thrown by the datasource classes are wrapped in this exception. The isInvalidSelect means that the command (usually a select) passed to the underlying data system was an invalid command. This is an expected possibility when processing multiple data sources. A SQL select will be garbage to an XPath select and vice versa.
