Taxonomy of BPEL Faults
A bpel fault has a fault name, which is a qname (name qualified with a namespace),
and a possible messageType.
There are two categories of faults in BPEL: business faults and runtime faults.
Business faults are application specific faults and occur when
an explicit <throw> activity is executed or an <invoke> activity gets a fault
as response. The fault name of a business fault is specified by the BPEL process and
the messageType, if one exists, is defined in the WSDL.
Runtime faults are not user defined and will not
appear in the WSDL for a process or service. The BPEL spec defines 11
standard faults: selectionFailure, conflictingReceive,
conflictingRequest, mismatchedAssignmentFailure, joinFailure,
forcedTermination, correlationViolation, uninitializedVariable,
repeatedCompensation and invalidReply. They are all in the namespace
"http://schemas.xmlsoap.org/ws/2003/03/business-process/" and are
typeless, meaning they don't have associated messageTypes. The Oracle
BPEL Process Manager also introduces two more runtime faults:
bindingFault and remoteFault. They are in the namespace of
"http://schemas.oracle.com/extension" and are associated with an Oracle
defined messageType "RuntimeFaultMessage". The WSDL that defines the
RuntimeFaultMessage messageType is available in the
c:/orabpel/system/xmllib directory.
RemoteFault is retryable. It has the following possible fault codes
| FaultCode |
Reason |
| ConnectionRefused |
The remote server is not up |
| WSDLReadingError |
Fail to read WSDL |
| GenericRemoteFault |
Generic remote fault |
BindingFault is not retryable. It has the following possible fault codes:
| FaultCode |
Reason |
| VersionMismatch |
The processing party found an invalid namespace for the SOAP Envelope
element |
| MustUnderstand |
An immediate child element of the SOAP Header element that was either
not understood or not obeyed by the processing party contained a SOAP mustUnderstand
attribute with a value of "1" |
| Client.GenericError |
Generic error at client side |
| Client.WrongNumberOfInputParts |
input message part number mismatch |
| Client.WrongNumberOfOutputParts |
output message part number mismatch |
| Client.WrongTypeOfInputPart |
input message part type error |
| Client.WrongTypeOfOutputPart |
output message part type error |
| Server.GenericError |
Generic error at server side |
| Server.NoService |
Server is up but no service |
| Server.NoHTTPSOAPAction |
Request is missing HTTP SOAP Action |
| Server.Unauthenticated |
Request is not authenticated |
| Server.Unauthorized |
Request is not authorized |
