Direct Known Subclasses:
NoEndPointException

public class AxisFault
extends RemoteException

An exception which maps cleanly to a SOAP fault. This is a base class for exceptions which are mapped to faults. SOAP faults contain

  1. A fault string
  2. A fault code
  3. A fault actor
  4. Fault details; an xml tree of fault specific stuff
