PM77833: WSA ACTION FROM WSDL OPERATION IS USED IN CASE OF A WEBSERVICE APPLICATION FAILURE WITH CICS OR USER ABEND

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a CICS WEBSERVICE application abends with CICS or USER abend
  or if an error in PIPELINE processing occurs, then CICS
  generates a SOapFault and uses the fault from WSDL-Operation.
  But wsa action from WSDL Operation is definitely not the right
  action, leading to wrong error handling in client processing.
  For example, after an abend ASRA, the response file contains
  the wsa:action: "http://xml.../FunctionTestService/v03/
  FunctionTestV03/getName/F/Fault/AccessDeniedException".
  But that's wrong, because there has been a CICS abend ASRA,
  not AccessDeniedException .
  CICS should rather send the wsa:action: "http://www.w3.
  org/2005/08/addressing/soap/fault" as recommended in
  WSAddressing specification and should not use a modelled
  fault from WSDL.

  ****************************************************************
  When CICS webservice application abends with CICS or User
  abend, or if an error in PIPELINE processing occurs,
  CICS generates a SoapFault and uses the fault action
  from WSDL Operation. The client uses information in
  action-header for further processing, the wrong action leads
  to confusion and to incorrect error handling. For CICS problems
  or User abends, CICS should use a default action
  (http://www.w3.org/2005/08/addressing/soap/fault) described
  in WS-Addressing Specification (http://www.w3.org/TR/
  ws-addr-soap/). But should never use a fault from WSDL.
  

Problem conclusion

• DFHPISF and DFHPIA1 have been changed to enhance the EXEC
  CICS SOAPFAULT processing so that CICS can detect whether the
  Fault is for a CICS reported problem or not. If it is, the
  subsequent WS-Addressing processing returns the default
  action defined in WSA Specification.
  
  CICS Transaction Server for z/OS Version 4 Release 2
  Web Services Guide, SC34-7191-02 has been altered in
  Chapter 6('Creating the web services infrastructure')
  under the heading of 'Containers used in the pipeline'
  to include a new context container that indicates the
  type of SOAP fault CICS creates.
  
  The description of the new container has been appended
  to the end of section 'Context containers':
  
  "DFHWS-FAULT container
  
  DFHWS-FAULT is a container of DATATYPE(BIT) that holds
  information about the type of SOAP fault CICS generates.
  
  The container holds a binary fullword that indicates the
  fault type that can be used in further processing for a
  web service response:
  
  1
  The most recent SOAP fault was for a CICS fault (for
  example, CICS or user abend).
  
  2
  The most recent SOAP fault was for an application fault.
  
  The container is deleted when you issue the EXEC CICS
  SOAPFAULT DELETE command. If a second or new SOAP fault
  is created, CICS updates the new container appropriately.
  
  You cannot change the contents of this container."
