CX_SXML_PARSE_ERROR-Error while parsing an XML stream: 'undeclared namespace prefix'.

[karuna_gangireddy]

Hi,

I am trying to consume web service in  ABAP . I need to pass SOAP header with the authentication along with SOAP body. I have used if_wsprotocol_ws_header interface to pass header but getting the PARSE error.

This is what I did:

- Created ABAP proxy from external WSDL, which in my case is Sales Force.

- Created logical port in SOAMANAGER.

- Executed the report calling the PROXY I created.

REPORT  ztest.

try.

*     instantiate the object reference

       if proxy_so is not bound.

*        create object proxy_

*        get WS_HEADER protocol

          data: ws_header type ref to if_wsprotocol_ws_header.

          ws_header ?= proxy_so->get_protocol('IF_WSPROTOCOL_WS_HEADER').

*        Additional Header

          concatenate

*          '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cre="http://soap.sforce.com/schemas/class/Creat           eSAPSalesOrder">'

           '<soapenv:Header>'

           '<cre:SessionHeader>'

           '<cre:sessionId>' result-session_id '</cre:sessionId>'

           '</cre:SessionHeader>'

           '</soapenv:Header>' into l_string  RESPECTING BLANKS.

*         convert to xstring

           l_xstring = cl_proxy_service=>cstring2xstring( l_string ).

           if l_string is not initial.

*            create iXML DOM document from XML xstring

              call function 'SDIXML_XML_TO_DOM'

                 exporting

                    xml           = l_xstring

                 importing

                    document      = xml_document

                 exceptions

                    invalid_input = 1

                    others        = 2.

              if sy-subrc = 0 and  xml_document is not initial.

                 xml_root = xml_document->get_root_element( ).

                 xml_element ?= xml_root->get_first_child( ).

*               add header element by element to SOAP header

                 while xml_element is not initial.

                    name = xml_element->get_name( ).

                    namespace = 'http://soap.sforce.com/'. "xml_element->get_namespace_uri( ).

                    ws_header->set_request_header(

                                name = name

                                namespace = namespace

                                dom = xml_element ).

                    xml_element ?= xml_element->get_next( ).

                 endwhile.

              endif.

           endif.

          catch cx_ai_system_fault into exc.

              msg = exc->get_text( ).

   endtry.

*  soap body using abap proxy class.

   data: input_so  type zwscreate_sales_order_request,

           output_so type zwscreate_sales_order_response.

*  Input value

    input_so-quote_number   = '2016-111111'.

try.

*   call the method (web service call)

      call method proxy_so->create_sales_order

        exporting

          input  = input_so

        importing

          output = output_so.

     catch cx_ai_system_fault into exc.

        msg = exc->get_text( ).

endtry.

In the above catch I am getting the PARSE error. I know it is from the header section that I created. But I am not able to find where is the error. Can anyone please help me out? I was also able to see the error logs in SOAMANAGER but not able to pin point the error.

Thanks in advance,

Karuna

Hi hatshepsut,

Me too.

Meet the undeclared namespace prefix error in webservice when trace it in soamanager.

Did you fixed it?
