* An exception that signals that a SOAP exception has
* occurred. A SOAPException object may contain a
* String that gives the reason for the exception, an
* embedded Throwable object, or both. This class
* provides methods for retrieving reason messages and for
* retrieving the embedded Throwable object.
*
* Typical reasons for throwing a SOAPException
* object are problems such as difficulty setting a header, not
* being able to send a message, and not being able to get a
* connection with the provider. Reasons for embedding a
* Throwable object include problems such as input/output
* errors or a parsing problem, such as an error in parsing a
