+/**
+ * An exception that signals that a SOAP exception has occurred. A
+ * <code>SOAPExceptionImpl</code> object may contain a <code>String</code>
+ * that gives the reason for the exception, an embedded
+ * <code>Throwable</code> object, or both. This class provides methods
+ * for retrieving reason messages and for retrieving the embedded
+ * <code>Throwable</code> object.
+ *
+ * <P> Typical reasons for throwing a <code>SOAPExceptionImpl</code>
+ * 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 <code>Throwable</code>
+ * object include problems such as input/output errors or a parsing
+ * problem, such as an error in parsing a header.
