PK56688: DFHWBCL ADDS LEADING ZEROES TO THE PORT NUMBER ON A URI USED ON AN EXEC CICS INVOKE WEBSERVICE

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible.

Error description

• When an EXEC CICS WEBSERVICE is invoked using a URI containing a
  port number other than the default CICS is padding the port
  number with leading zeroes.
  E.G. If a URI of http://www.aaa.com:88 is specified then CICS
  sends the URI as http://www.aaa.com:00088
  
  This can be rejected by some servers resulting in message
   DFHPI0602 31/10/2007 12:24:11 xxxxxxxx The CICS SOAP handler
  failed to parse a message. The parser error code is 0. The
  DFHPIEP return code is 8. The error was found at
  offset 1 into the message.

  ****************************************************************
  A CICS application is issuing an EXEC CICS INVOKE WEBSERVICE
  command supplying a port number that is not a default HTTP
  port number (not 80, or 443 for HTTPS). In this particular
  case it was 88. As the port number is less than 5 digits long
  the port number in the HTTP HOST header was padded with
  leading zeros, appearing as 00088. This caused the Web Service
  provider to reject the request because it cannot handle leading
  zeros. The non-SOAP error response led to message DFHPI0602 when
  CICS tried to parse the SOAP response.

• FIX AVAILABLE BY PTF ONLY
  

Comments

• DFHWBCL has been updated to no longer pad port numbers with
  leading zeros in the HTTP Host header for all outbound HTTP
  requests.
