PI88520: CICS WEB CLIENT SENDS JSON DATA IN EBCDIC INSTEAD OF ASCII

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A CICS application constructs a JSON message within a container
  and issues an EXEC CICS WEB CONVERSE command to send that JSON
  data to a remote server.  The application specified a MEDIATYPE
  of application/json;v=3.
  
  DFHWBCL incorrectly determines that the supplied mediatype is
  not a text based type.  This causes the JSON data to be sent
  without being converted from EBCIDC to ASCII.
  
  The remote server is then unable to process the JSON message.

  * PROBLEM DESCRIPTION: MEDIATYPE parameter on EXEC CICS WEB    *
  *                      SEND and CONVERSE commands may be       *
  *                      interpreted incorrectly.                *
  ****************************************************************
  In the reported problem, an EXEC CICS WEB CONVERSE command
  contained a MEDIATYPE parameter of: application/json;v=3.
  This is legal syntax but having the ';v=3' caused routine
  wbcm_determine_mediatype to not identify the associated payload
  as being text but binary.  When the payload was placed into a
  container, no conversion to UTF-8 text was performed.  The data
  was then sent to the server in EBCDIC.
  

Problem conclusion

• DFHWBCL has been amended to correctly identify the MEDIATYPE
  parameter, including ones that have data past the semi-colon.
