PM12825: DUPLICATE SOAP-ENV NAMESPACE IN XML RESPONSE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The client declares the SOAP-ENV namespace
  a second time on the empty header element:
  ---------------------------------------------------------------
  <SOAP-ENV:Envelope>
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
       xmlns:xsd="http://www.w3.org/2001/XMLSchema"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <SOAP-ENV:Header>
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  </SOAP-ENV:Header>
  ---------------------------------------------------------------
  .
    CICS responds with XML that contains a duplicate namespace.
  ---------------------------------------------------------------
  <SOAP-ENV:Envelope>
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  ---------------------------------------------------------------
  .
    This duplicate namespace causes problems for the client.

  *                      DFHMLPC xml parser when processing a    *
  *                      SOAP request.                           *

  * RECOMMENDATION:                                              *
  ****************************************************************
  CICS generates a bad SOAP message containing a
  duplicate SOAP-ENV namespace. This is because the request
  message contained a Header element declaring the same namespace
  as the one defined on the Envelope element and the CICS SOAP
  handler was specified to run twice in the pipeline
  configuration file.
  
  This results in DFHPISN merging the namespaces in the Header
  element with the namespaces in the Envelope element, and
  placing them in the DFHWS-XMLNS container.
  
  The z/OS system XML parser detects the invalid XML response
  message and returns a XML parser exception with reason code
  3001, indicating:
  
  3001 XRSN_NS_DUPLICATE
  Duplicate namespace declaration found.
  

Problem conclusion

• DFHPISN has been changed so that the contents of the
  DFHWS-XMLNS container are rebuilt after completing Header
  processing ensuring that the duplicate namespace will
  not be passed to the rest of the pipeline when it is called by
  a provider pipeline and when it is not a terminal handler.
