AxisC++ 1.5 fail retrieve string arrays in SOAP message?

Hi,

Again with my Axis C++ 1.5 client running against the Axis JAVA 1.3 
server experiment:
I have a webservice has interface : String[] search(String getIgnored)
the java client handle it perfectly by the way.

My c++ client is a bit funky though. The stub generated has following 
code (I add some
debuging output):
xsd__string_Array Search::search(xsd__string Value0)
{
    xsd__string_Array RetArray = {NULL, 0};
    const char* pcCmplxFaultName;
    try
    {
        if (AXIS_SUCCESS != m_pCall->initialize(CPP_RPC_PROVIDER))
            return RetArray;
    if (NULL==m_pCall->getTransportProperty("SOAPAction",false))
    {
        m_pCall->setTransportProperty(SOAPACTION_HEADER , "");
    }
        m_pCall->setSOAPVersion(SOAP_VER_1_1);
        m_pCall->setOperation("search", "http://ws.search.simdesk.com");
        applyUserPreferences();
        m_pCall->addParameter((void*)Value0, "criteria", XSD_STRING);
        if (AXIS_SUCCESS == m_pCall->invoke())
        {
            if(AXIS_SUCCESS == m_pCall->checkMessage("searchResponse", 
"http://ws.search.simdesk.com"))
            {
                // tyang changed following line - it complains about 
type conversion is invalid
                //RetArray = 
(xsd__string_Array&)m_pCall->getBasicArray(XSD_STRING, "searchReturn", 0);
                Axis_Array arr = m_pCall->getBasicArray(XSD_STRING, 
"searchReturn", 0);
                xsd__string_Array sarr = { (xsd__string *) arr.m_Array, 
arr.m_Size };
                RetArray.m_Array = (xsd__string *) arr.m_Array;
                RetArray.m_Size = arr.m_Size;
                std::cout << "result.size = " << RetArray.m_Size << endl;
                std::cout << "result: ";
                for (int i = 0; i < RetArray.m_Size; i++)
                {
                    std::cout << RetArray.m_Array[i] << "; 
";                std::cout << endl;
            }
        }
    m_pCall->unInitialize();
        return RetArray;
    }
    catch(AxisException& e)
    {
        int iExceptionCode = e.getExceptionCode();
        if(AXISC_NODE_VALUE_MISMATCH_EXCEPTION != iExceptionCode)
        {
            throw SoapFaultException(e);
        }
        ISoapFault* pSoapFault = (ISoapFault*)
            
m_pCall->checkFault("Fault","http://172.16.53.33:8080/simdesk/services/Search" 
);
        if(pSoapFault)
        {
            m_pCall->unInitialize();
            throw SoapFaultException(e);
        }
        else throw;
    }
}

Plus, the SOAPMonitor reporting following request:
<?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">
  <SOAP-ENV:Body>
    <ns1:search xmlns:ns1="http://ws.search.simdesk.com">
      <criteria xsi:type="xsd:string">asdr</criteria>
    </ns1:search>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

And following response:<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Body>
    <ns1:searchResponse 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:ns1="http://ws.search.simdesk.com">
      <searchReturn soapenc:arrayType="soapenc:string[6]" 
xsi:type="soapenc:Array" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
        <searchReturn xsi:type="soapenc:string">eqre.pdf</searchReturn>
        <searchReturn xsi:type="soapenc:string">another.txt</searchReturn>
        <searchReturn xsi:type="soapenc:string"></searchReturn>
        <searchReturn xsi:type="soapenc:string">~/blah.h</searchReturn>
        <searchReturn xsi:type="soapenc:string">asdf</searchReturn>
        <searchReturn xsi:type="soapenc:string" xsi:nil="true"/>
      </searchReturn>
    </ns1:searchResponse>
  </soapenv:Body>
</soapenv:Envelope>

What have I done wrong? :-(

Thanks for any help or advice in advance!
Tao

Hi,

There were still some outstanding issues with arrays at the release of Axis
C++ 1.5.   There has since been a lot of work in improving the design and
workings of arrays, which is available in the 1.6 nightly builds - you may
wish to try these to see if your problems have already been resolved.

Regards,
Adrian

Just in case someone else may want to know my lesson here.

It turns out this is happening because I always return a array whose 
last item is null - I was paranoid before I dig into Axis C++ and afraid 
of it won't know the size of the array so that that null is put in as 
boundary indicator. However, nicely the Axis C++ does return the array 
size; but fail to cope with my "null" boundary indicator and thought 
error has happened.

This does raise a question though: why Axis C++ can't handle a "null" 
item? the java version process this nicely by the way.

cheers,
Tao

Oops, I forget to say. Even the valid response is observed through
the SOAPMonitor, the c++ client code is always reporting:
"result.size = 0"
What could be preventing it extract the strings from the message?

Thanks,
Tao
