PI71031: WEBSERVICES FAIL WITH MESSAGES DFHPI0401, DFHPI0503, DFHPI0997, AND "BASIC AUTHENTICATION FAILURE" HTTP 401 RESPONSE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running in an environment with both SSL and non-SSL
  webservices, and after application of the PTF UI40033 for APAR
  PI64504, there are failures.  These can present as messages:
  
  DFHPI0401 applid tran The CICS pipeline HTTP transport
     mechanism failed to send a response or receive a request
     because the connection was closed.
  DFHPI0503 applid tran The CICS Pipeline Manager has failed to
     send a response on the underlying transport TRANSPORT: HTTP,
     PIPELINE: PIPE
  DFHPI0997 applid tran PIPE The CICS pipeline manager has
     encountered an error: unidentified problem.
  .
  or with trace entries:
  
  PI 0A27 PIIS  *EXC* TRANSPORT_FAILED
  SO 080C SOSE  *EXC* SYSTEM_SSL_ERROR      GSK_ERR_SOCKET_CLOSED,
     SECURE_SOC_INIT,EXCEPTION,CONNECTION_CLOSED,1A4 (for SSL)
  AP 4522 WBXN  *EXC* RECEIVE_ERROR
  .
  You have configured your webservices with Basic Authentication.
  You are using the string : 'Authorization: Basic
  USERID:PASSWORD' (with the credential string possibly encoded),
  but the trace data shows that you receive a 401 response of
  "Basic Authentication Error".
  
  
  
  
  This also causes a SOAP reponse message to change from
  
  <SOAP-ENV:Envelope
   xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
   xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
     <SOAP-ENV:Body>
  
        :
        :
        :
        :
  
     </SOAP-ENV:Body>
  </SOAP-ENV:Envelope>
  
  
  to
  
  
  <soapenv:Envelope
   xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
      <SOAP-ENV:Body>
  
        :
        :
        :
        :
  
     </SOAP-ENV:Body>
  </soapenv:Envelope>
  
  
  which wil cause a parsing error on the client.

  ****************************************************************
  After applying PTF UI40033 for APAR PI64504 various parsing
  errors are seen.
  CICS receives an inbound SOAP message which does not use
  namespace prefix SOAP-ENV. DFHPISN parses the message and
  invokes an apphandler program that causes a context switch to
  occur.
  On return from the apphandler program, DFHPISN recreates
  the DFHWS-XMLNS container with the namespace information
  from the input message.
  CICS builds a response Body element with namespace prefix
  SOAP-ENV. As this is not defined in the DFHWS-XMLNS container,
  CICS creates a response message that is not well formed.
  After the response is sent, the badly formed XML causes errors
  in subsequent processing.
  

Problem conclusion

• UI40033
  DFHPISN is changed so it does not recreate the DFHWS-XMLNS
  container on return from an apphandler program.
  The XML response message from CICS is well formed with
  namespace prefix SOAP-ENV correctly defined.
