RE: Problem deserializing SOAP response in Axis C++ client

OK, I think I see my mistake. The SOAP response sent by the webservice has character entities (< and >) instead of "<" & ">" in its xml tags.

Thus the line

is actually -

SOAP Response from webservice

<env:Envelope
    xmlns:env = "http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
    xmlns:soapenc = "http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsd = "http://www.w3.org/2001/XMLSchema">
    <env:Body>
        <n1:lookupProductResponse xmlns:n1 = "http://www.cardinal.com/distribution/webservices"><result xsi:type="xsd:string">TEST</result></n1:lookupProductResponse>
    </env:Body>
</env:Envelope>

Any idea how to enable parsing of character entity tags as xml nodes in Axis C++ (actually xerces 2.6) client?

There is a function setCreateEntityReferenceNodes(bool) mentioned axis docs (%AXIS_EXTRACT%/xerces-c_2_6_0-windows_nt-msvc_60/doc/html/apiDocs/classAbstractDOMParser.html#z452_5), can this be used in this case?

Thanks,

Hi Dushshantha,

Please find the attached wsdl.

When debugged AxisXmlParserXerces code with a xerces-c_2_6D.dll, it stopped throwing exception like xerces-c_2_2_0.dll (the dll which I was using earlier). However, getElementAsString() is now returning 0 value after deserializing <result xsi:type="xsd:string">TEST</result>.

Some pointers -

In getElementAsString() function, getXSDType() (SoapDeSerializer.cpp: line # 3110) returns XSD_UNKNOWN. This ultimately results in returning 0 from getElementString (instead of "TEST").

At line # 3106 in SoapDeSerializer.cpp (m_pNode = m_pParser->next ()) the m_type of node pointer shows END_ELEMENT instead of expected START_ELEMENT. This results in returning type as XSD_UNKNOWN.

Also, for some reason pElement->m_pchAttributes array also shows up empty in getXSDType() function.

This seems to be a bug. If so, is there any work already done on it?

Thanks & regards,

Linesh

Hi Linesh,

It would be better if you can attach the wsdl file you are using for that then I can generate the client and test with MockServer.

And you can use MockServer for Client side testing. Please refer to ..\ws-axis\c\tests\auto_build\UnitTest_Readme.txt for more information.

Thanks,

Dushshantha

Hi,

I am trying to communicate with a J2EE webservice running on Bea Weblogic webserver 8.1 SP3. The client side has Axis C++. I am getting error while reading the SOAP response sent by the webservice. The exception occurs on calling getElementAsString function (after checkMessage return successful, line 3105: at m_pNode = m_pParser->next ()).

The code is exactly similar to the one provided with C++ samples.

if (AXIS_SUCCESS != m_pCall->initialize(CPP_RPC_PROVIDER))
   return *Ret;

if (NULL==m_pCall->getTransportProperty("SOAPAction",false))
{
  m_pCall->setTransportProperty(SOAPACTION_HEADER , "ProductLookupService#lookupProduct");
}
  m_pCall->setSOAPVersion(SOAP_VER_1_1);

setUsername("user");
setPassword("password");

m_pCall->setOperation("lookupProduct", "http://localhost/distribution/webservices");

applyUserPreferences();
m_pCall->addParameter((void*)lpParam, "xmlRequest", XSD_STRING);

if (AXIS_SUCCESS == m_pCall->invoke())

{



if(AXIS_SUCCESS==m_pCall->checkMessage("lookupProductResponse", "http://www.cardinal.com/distribution/webservices"))
{
     char sTemp[1024]="";
     sprintf(sTemp, m_pCall->getElementAsString("result", 0));    //**** EXCEPTION THROWN HERE***
}

The response received is as below (Trapped using Mindreef SOAPScope).

Request sent (It sends an XML string in parameter "xmlRequest") -

<?xml version='1.0' encoding='utf-8' ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Rsposne received (Output parameter name is "result")-
