public class ServiceException

A service exception used to indicate that a service problem occurred.

A ServiceException object is created by the Framework or service implementation to denote an exception condition in the service. A type code is used to identify the exception type for future extendability. Service implementations may also create subclasses of ServiceException. When subclassing, the subclass should set the type to SUBCLASSED to indicate that ServiceException has been subclassed.

This exception conforms to the general purpose exception chaining mechanism.
