KErrSenNotInitialized error while accessing web service, what am I doing wrong?

[RaimondasL]

I am trying to get a program running that accesses a web service. I am using S60v3 MR SDK and running my program on emulator. I generated the skeleton code from WSDL (http://www.ignyte.com/webservices/ig...ions.asmx?wsdl) using web service code generation utility and wrote my code according to the tool usage manual. My code is:

_LIT (KServiceEndpoint, "http://www.ignyte.com/webservices/ignyte.whatsshowing.webservice/moviefunctions.asmx");
CSenXmlServiceDescription *pServiceDesc = CSenXmlServiceDescription::NewLC(KServiceEndpoint, KNullDesC8());
pServiceDesc->SetFrameworkIdL(KDefaultBasicWebServicesFrameworkID);
MovieCallback* pObserver = MovieCallback::NewLC();
CMovieInformationService* pService = CMovieInformationService::NewLC(*pObserver,*pServiceDesc);

RGetTheatersAndMoviesResponse result;
RGetTheatersAndMovies param;
_LIT(KZip,"01821");
param.iZipCode = HBufC::NewL(100);
*(param.iZipCode) = KZip;
param.iRadius = 5;
CSenSoapFault* fault = NULL;
pService->GetTheatersAndMoviesL(param, result, &fault); // <--- this calls iConnection->SubmitL(*soapRequest, responseStr); where it gets the KErrSenNotInitialized error

BTW, the emulator does not even show a warning about accessing web service and does not show "Access Point Selection" dialog that is shown during network accesses. However, the emulator accesses web fine, so it's not a network connection issue.

I also succeeded to get the AddressBook web service example running - it also accesses web service fine in the emulator. Unfortunately, AddressBook uses different framework (Liberty/ID) and is overall too complex, so I can't use it to access the service above.

Any suggestions would be appreciated.

For anyone who might be interested, the issue was that after

CMovieInformationService* pService = CMovieInformationService::NewLC(*pObserver,*pServiceDesc);

the program needs to wait for SetStatus(KSenConnectionStatusReady) callback. It is an empty skeleton method that needs to be implemented in generated service callback file. This callback needs to occur before calling

pService->GetTheatersAndMoviesL(param, result, &fault);

Now my program works fine.

i have the same problem. how do you wait for "SetStatus(KSenConnectionStatusReady) callback" ?

Well, my solution was pretty much a hack, but here it is:

In your web service callback, you set a flag:

void YourWebServiceCallback::SetStatus(const TInt aStatus)
{
iConnectionState = aStatus;
}

In your app somehow now you wait for this flag to become set. I just had another command that user selected in menu:

case EWebServiceCommand2:
{
if (pObserver->iConnectionState == KSenConnectionStatusReady)
{
// Do your stuff
}
}

But you can use some other way to wait for a flag. Or maybe you can setup active object and send it message from callback.

and does now emulator show warning about accessing web service and accesspoint dialog?

[RaimondasL]

Sorry, I missed your message. Yes, I believe emulator should show a warning about accessing web service and access point dialog if you wait for callback.

If I misunderstood your question, let me know.

Hi
Its been some months since this conversation took place and I am hoping someone can help me with this same problem.

I am trying to access a simple test calculator web service running on a local glassfish application server and I am getting the same KErrSenNotInitialized error. I have tried waiting for the SetStatus() callback as mentioned above but it never seems to be called.
I also ran a packet sniffer (wireshark) and did not capture any packets from my client running on the emulator meaning there is no attempt to even establish the connection. However I can capture packets when using the browser on the emulator.

My client also doesn't show any access point dialog or warning on accessing the web service.

here is some sample code of my client:

//inside the callback class
void CCalculatorWSServiceServiceConsumer::SetStatus(const TInt aStatus)
{
iConn = aStatus;
}

//inside HandleCommandL()

case EWSTest1Command1:

CAknInformationNote * informationNote = new ( ELeave ) CAknInformationNote;
_LIT8(KServEndpoint,"http://ipAddressOfServer/CalculatorWSService/CalculatorWS");
pServiceDesc =CSenXmlServiceDescription::NewL(KServEndpoint);
pServiceDesc->SetFrameworkIdL(KDefaultBasicWebServicesFrameworkID);
pObserver = CCalculatorWSServiceServiceConsumer::NewLC();
a.iI = 5;
a.iJ = 6;

pService = CCalculatorWSServiceService::NewLC(*pObserver,*pServiceDesc);
break;



case EWSTest1Command2:


CAknInformationNote * informationNote1 = new ( ELeave ) CAknInformationNote;
TRAPD(myError,result = pService->AddL(a));
if(pObserver->iConn == KSenConnectionStatusReady)
{
if (myError == KErrSenSoapFault)
{
_LIT(KMyMessage,"Oh dear some error");
informationNote1->ExecuteLD(KMyMessage);
}
else
{
TBuf<10> iString;

iString.Num(result.iReturn);
informationNote1->ExecuteLD(iString);
}

[frizi]

you must wait for (pObserver->iConn == KSenConnectionStatusReady) BEFORE calling pService->AddL(a)

so it means
1. pService = CCalculatorWSServiceService::NewLC(*pObserver,*pServiceDesc);
2. wait for pObserver::SetStatus call (I use CActiveSchedulerWait for this)
3. check pObserver->iConn == KSenConnectionStatusReady
4. if ok, call pService->AddL(a) and after that you will see IAP selection dialog and packet traffic (you can use emulator->Tools->Diagnostics for watching traffic...)

I have have moved my if statement to before calling the web service method so it reads:

case EWSTest1Command2:
CAknInformationNote * informationNote1 = new ( ELeave ) CAknInformationNote;

if(pObserver->iConn == KSenConnectionStatusReady)
{
TRAPD(myError,result = pService->AddL(a));
....

However, I am still not getting the access point dialog or any sign of a connection ever being initialized.
