XML Parse problem consuming external webservice

[Former Member]

Hi all,

I'm testing consuming an external webservice from a WAS 6.40 client. I generated an ABAP proxy for it .

I managed to get the correct soap request out and receiving the response, but while parsing the SOAP XML response back into the output parameter, I'm running into a parse error :

- <CX_XMS_SYSTEM_ERROR>

<ID>PARSE_APPLICATION_DATA</ID>

<P1>Response Message</P1>

<P2>CX_ST_MATCH_TYPE</P2>

<P3>/1SAI/TXS00000000000000000003</P3>

<P4>XML Bytepos.: 354 XML Path: root(1)ns1:checkValidSerialNumbersResponse(1)checkValidSerialNumbersReturn(1) Error Text: System expected a value for the type g</P4>

<INFO />

<CATEGORY>XIProxy</CATEGORY>

<AREA>ABAP</AREA>

<RETRY>M</RETRY>

</CX_XMS_SYSTEM_ERROR>

- <CX_XMS_SYSERR_PROXY>

<CO_AREA_ABAP>ABAP</CO_AREA_ABAP>

</CX_XMS_SYSERR_PROXY>

</cls:CX_XMS_SYSERR_PROXY>

- <cls:CX_ST_MATCH_TYPE id="o163">

The response parameter is defined as xsd:string ( and string in the generated ABAP structure ).

IF the byteposition is correct there would be a problem

with the '?' characeter being in the response.

What does the datatype 'g' mean ?

see also in the error message :

<ACTUAL_NAMESPACE />

<ACTUAL_VALUE />

</CX_ST_MATCH>

- <CX_ST_MATCH_TYPE>

<EXPECTED_TYPE>g</EXPECTED_TYPE>

</CX_ST_MATCH_TYPE>

Any ideas ? Using 2 other soap clients give no issue what soever...:(

Hi all

For those who are interested , I solved on my own.

The datatype 'g' refers to string data type ( see internal codes for ABAP data types ).

The parse error was generated in the internal simple XSLT transformation : This transformation is again based upon the WSDL file that was used for generating te proxy and although it passed the SAP checks, it was apparently not in a format support by SAP.

In brief : All types must be defined as complex elements , even if they are as simple as an input string and an output string

Hope it helps somebody.

Hi,

I'm encountering exactly the same problem. The response structure generated out of the WSDL file looks like this:

type begin of ZAV_DO_SINGLE_RECORD_SOAP_OUT,
          controller type PRXCTRLTAB,
          DO_SINGLE_RECORD_RESULT type string,
       end of ZAV_DO_SINGLE_RECORD_SOAP_OUT.

creating my own structure for ls_response and using this in

    CALL METHOD lo_clientProxy->DO_SINGLE_RECORD
      EXPORTING
        INPUT  = ls_request
      IMPORTING
        OUTPUT = ls_response.

leads to a type mismatch syntax error. how did you solve this issue, as I cannot modify the generated proxy structure?

thanks a lot for your help!

Hi Robert,

You need to edit the wsdl file first and make sure all your paramters are defined as complex parameters and then regenerate the proxy based upon this changed wsdl file

This is WSDL. Could you please tell if anything is wrong in WSDL?
