odd behaviour wile running axis service on VS.NET Managed and Native code client

[Mohit Gupta <mo...@yahoo.com>]

Hi,

We are seeing some odd behavior while accessing our
Web Service written in Axis 1.2. The managed code C++
client auto-generated by VS.NET works perfectly, but
the native code C++ client auto-generated by VS.NET
fails completely. The SOAP requests generated by both
the clients are identical, and the SOAP responses
generated by the web service are also identical in
both cases. The modified WSDL files generated by both
the clients are also identical.

Specifically, the native code C++ client fails in the
BeginParse() method of the CSoapSocketClient template
class which is auto-generated by VS.NET:

int _tmain(int argc, _TCHAR* argv[])
{
	CServerClassService serverClassService ;
	CoInitialize(NULL);

	int i = 10, x;
	HRESULT h;

	h = serverClassService.getIntValue(i, &x);
	
	printf("value  of x is %x", x);
	return 0;
}

The program prints 0xcccccccc, and h is set to E_FAIL.

The server and client WSDL files and the SOAP
request/response messages are attached below. Any
illumination of this situation will be much
appreciated.

thanks,
Manoj
