Hi,

its quite difficult to answer you!! I have not understand so much!!

Do you actually need help to use gSoap in Qt?
Do you need help to communicate from a Qt app to a gSoap one?

I can point you in both directions since I have intensively developed using Qt and gSoap.

Using gSoap in QT (a sample code)...
Qt Code: 
  1. #include "src/gsoap/soapOtalierService.h"
  2.  
  3. int main(int argc, char *argv[])
  4. {
  5. 	QApplication a(argc, argv);
  6.  
  7. 	int            soapMessage = SOAP_OK;
  8. 	std::string    queryString = getenv("QUERY_STRING");
  9. 	OtalierService service;
  10.  
  11. 	if(queryString == "wsdl")
  12. 	{
  13. 	    service.http_content = "text/xml";
  14. 	    soap_response(&service, SOAP_FILE);
  15.  
  16. 	    FILE *fd      = 0;
  17. 	    fd            = fopen("Otalier.wsdl", "rb");
  18. 	    bool fileRead = true;
  19. 	    while(fileRead)
  20. 	    {
  21. 	        size_t r = fread(service.tmpbuf, 1, sizeof(service.tmpbuf), fd);
  22. 	        if (!r || soap_send_raw(&service, service.tmpbuf, r))
  23. 	        {
  24. 	            fileRead = false;
  25. 	        }
  26. 	    }
  27.  
  28. 	    fclose(fd);
  29. 	    soap_end_send(&service);
  30.  
  31. 	}else
  32. 	{
  33. 	    //soap_set_omode(&service, SOAP_C_UTFSTRING);
  34. 	    service.serve();
  35. 	}
  36.  
  37. 	QTimer::singleShot(0, qApp, SLOT(quit()));
  38. 	a.exec();
  39.  
  40. 	return soapMessage;
  41. }

The code speaks by itself the trick using Qt and events is in using

QTimer::singleShot(0, qApp, SLOT(quit()));
a.exec();

which is going to do only an execution of the code and terminate the whole thing, the rest is the gSoap code needed. The executable is served as a cgi with apache.

To communicate the QT app with a gSoap service can be done in some ways, one could be write the entire SOAP XML request and make a request to the service. The other aproach is write a client using gsoapcpp2 and the last one is just passing cgi vars, I used the last one at my first atempt but later on I became more sophisticated

Hope this helps
