PH57214: UTF-8 CHARS CONVERTED INCORRECTLY WHEN CONTENT-TYPE HEADER RETURNED BY A WEB SERVICE HAS AN ACTION FIELD INCLUDED IN IT.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a web server returns a response that includes an action
  field within the Content-Type header UTF-8 characters are
  being converted incorrectly.
  
  An Example of a response returned is :
  
  HTTP/1.1 200 OK
  Content-Type: application/soap+xml; charset=UTF-8;
  action="xxx.xxx.xxx.xxx/soap12/xxxxResponse"
  
  Content-Length: 1421
  <?xml version='1.0' encoding='UTF-8'?>
  <soapenv:Envelope xmlns:soapenv>
  
  A CICS trace shows :
  
  AP 4800 CCNV  ENTRY - FUNCTION(VERIFY_IANA_CCSID)
         IANA_CCSID(UTF-8; action="http://xxx.xxx.xxx/WS/)
  
  AP 4801 CCNV  EXIT  - FUNCTION(VERIFY_IANA_CCSID)
  
         RESPONSE(EXCEPTION) REASON(IANA_CCSID_NOT_KNOWN)
         IBM_CCSID(0)
  
  i.e. we are treating UTF-8;action= ....  as the codepage. As
  this isn't a valid codepage we use ISO-8859-1 meaning that
  double byte UTF-8 characters are not converted correctly.

  * USERS AFFECTED: All CICS Users                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: CICS does not use the correct code page *
  *                      when converting a HTTP request when     *
  *                      the Content-Type header contains an     *
  *                      action value.                           *
  ****************************************************************
  CICS receives a HTTP request where the Content-Type header
  specifies an action after the charset.  When this is parsed by
  DFHWBCL it incorrectly passes the charset value and action
  appended to it when attempting code page conversion.
  
  An IANA_CCSID_NOT_FOUND exception occurs and conversion is
  performed using ISO-8859-1.  This will cause UTF-8 characters to
  be incorrectly converted.
  

Problem conclusion

• DFHWBCL has been updated to correctly find the end of the
  charset.
