PM24213: Characters lost when calling CICS web service

APAR status

• Closed as program error.

Error description

• Customer has a WEB service running on CICS. The input data to
  the service is in one codepage, and the output is in another.
  The output data is being corrupted when the service returns via
  the CICS pipeline.
  
  To fix this problem RBD will be changed so that the user
  can specify the codepage of the returned data. In addition, CICS
  service will be modified by an APAR so the RBD can specify the
  codepage of the data to be placed in the return container.

  ****************************************************************
  The application is trying to return international data from
  a single CICS web service. Normally CICS only supports a
  single CCSID which it uses to convert character data to
  UTF-8. Returned characters not in the single CCSID are
  getting lost or incorrectly converted.
  

Problem conclusion

• This change is in conjuction with a change from CICS for
  apar PM24403.
  
  This change implements servicelib.setCCSID(?ccsid?) which
  allows the service function to set a CCSID that will be used
  by the service wrapper and CICS to convert the character
  return data to UTF-8.
  
  This CCSID will override the COBOL compiler codepage
  parameter and the codepage in the wsbind file that CICS
  normally uses to convert data to UTF-8.
  
  Only a single CCSID can be set for the return and all
  returned character data will be converted using this CCSID.
  
  To enable this function, the CICS apar must be applied to
  the CICS region, this apar must be applied to RBD, and the
  build descriptor must use the symbolic parameter
  PROGRAMSETSCCSID=yes
