Unable to connect to GPRS using IAP

[kusumat]

Hi ,

I want to hide the pop up asking for IAP.

I've referred to HTTPTaskManager example that is available in wiki.
But i coundt connect to GPRS.

calling query from Appui and i have implemented query in responseview in y project

if (iResponseView->QueryIapL(iap, 0))
		{
		iEngine->SetIap(iap);
		iEngine->ConnectL();
		}

void CBlueIdClientEngine::ConstructL()
	{
	User::LeaveIfError(iSockServ.Connect());
	User::LeaveIfError(iConnection.Open(iSockServ));
	// Open RHTTPSession with default protocol ("HTTP/TCP")
	TRAPD( err, iSession.OpenL() );
	if (err != KErrNone)
		{

		HBufC* textResource = StringLoader::LoadLC(R_WEBCLIENT_IAP_CONF_ERR,
		err);
		CAknErrorNote* errorNote;
		errorNote = new (ELeave) CAknErrorNote;
		// Show the error Note with textResource loaded with StringLoader.
		errorNote->ExecuteLD(*textResource);
		// Pop HBuf from CleanUpStack and Destroy it.
		CleanupStack::PopAndDestroy(textResource);
		User::Leave(err);
		}
	LoadIapsL();
	//CBlueIdClientEngine* iEngine = CBlueIdClientEngine::NewL(*this);

	// Install this class as the callback for authentication requests. When 
	// page requires authentication the framework calls GetCredentialsL to get 
	// user name and password.
	InstallAuthenticationL(iSession);
	}

void CBlueIdClientEngine::LoadIapsL()
	{
	// open commdb
	CCommsDatabase* commDb = CCommsDatabase::NewL(EDatabaseTypeIAP);
	CleanupStack::PushL(commDb);

	// open IAP table
	CCommsDbTableView* commView = commDb->OpenIAPTableViewMatchingBearerSetLC(
			ECommDbBearerCSD | ECommDbBearerGPRS,
			ECommDbConnectionDirectionOutgoing);

	// search all IAPs
	if (commView->GotoFirstRecord() == KErrNone)
		{
		do
			{
			TIap iap;
			commView->ReadTextL(TPtrC(COMMDB_NAME), iap.iName);
			commView->ReadUintL(TPtrC(COMMDB_ID), iap.iId);
			User::LeaveIfError(iIAPs.Append(iap));
			}
		while (commView->GotoNextRecord() == KErrNone);
		}

	CleanupStack::PopAndDestroy(/*commView*/);
	CleanupStack::PopAndDestroy(/*commDb*/);

	}

void CBlueIdClientEngine::SetIap(const TUint32& aId)
	{
	iIap = aId;
	}
TBool CBlueIdClientEngine::IapSet() const

	if (iIap == 0)

	else

		}
	}

RArray<TIap>& CBlueIdClientEngine::Iaps()
	{
	return iIAPs;
	}

void CBlueIdClientEngine::ConnectL()
	{
	// this functionality is not applicable for the emulator
#ifndef __WINS__ 
	TBool connected = EFalse;

	// Lets first check are we already connected.
	TUint connectionCount;
	User::LeaveIfError(iConnection.EnumerateConnections(connectionCount));

	)
}


	

		

			

			
				
 calling connectL() from  IssueHTTPGetL
			
		
	
void CBlueIdClientEngine::IssueHTTPGetL(const TDesC8& aUri)
{
ConnectL();

TUriParser8 uri;
uri.Parse(aUri);

// Get request method string for HTTP GET
RStringF method = iSession.StringPool().StringF(HTTP::EGET,
		RHTTPSession::GetTable());

// Open transaction with previous method and parsed uri. This class will
// receive transaction events in MHFRunL and MHFRunError.
iTransaction = iSession.OpenTransactionL(uri, *this, method);

// Set headers for request; user agent and accepted content type
RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection();
SetHeaderL(hdr, HTTP::EUserAgent, KUserAgent);
SetHeaderL(hdr, HTTP::EAccept, KAccept);

// Submit the transaction. After this the framework will give transaction
// events via MHFRunL and MHFRunError.
iTransaction.SubmitL();

iRunning = ETrue;

// Load a string from the resource file 
HBufC* textResource = StringLoader::LoadLC(R_WEBCLIENT_CONNECTING);
iObserver.ClientEvent(*textResource);
CleanupStack::PopAndDestroy(textResource);
}

Hi shafali gupta,

So i need not to worry about all these function
can i directly put this in ConstructL of the httpengine class?
Thanks

Above code that i have posted is for setting up the connection only. You can craete the cnnection in your constructL() itslef as it is required to be done only once.

Hi,
when i set up the connection using th code below
it was working fine earlier.
but the same code not working.
when i debug point coes

iSession.OpenL();

it is giving HTTP-CORE 0 error

i have closed like this before opening

if(iSession)
	iSession.Close();

but still the first ref to iSession closes app

iSession.OpenL();
User::LeaveIfError(iSocketServ.Connect());
User::LeaveIfError(iConnection.Open(iSocketServ));
CCommsDatabase* commDB = CCommsDatabase::NewL(EDatabaseTypeIAP);
CleanupStack::PushL(commDB);
CCommsDbConnectionPrefTableView* commDBView =
commDB->OpenConnectionPrefTableInRankOrderLC(ECommDbConnectionDirectionOutgoing);
User::LeaveIfError(commDBView->GotoFirstRecord());
CCommsDbConnectionPrefTableView::TCommDbIapConnectionPref pref;
commDBView->ReadConnectionPreferenceL(pref);
TUint32 iapID = pref.iBearer.iIapId;
CleanupStack::PopAndDestroy(commDBView);
CleanupStack::PopAndDestroy(commDB);
TCommDbConnPref connectPref;
connectPref.SetIapId(iapID);
connectPref.SetDialogPreference(ECommDbDialogPrefDoNotPrompt);
connectPref.SetDirection(ECommDbConnectionDirectionOutgoing);
connectPref.SetBearerSet( ECommDbBearerGPRS | ECommDbBearerCdma2000 | ECommDbBearerLAN | ECommDbBearerCSD );
TInt errConnect = iConnection.Start(connectPref);

RStringPool strP = iSession.StringPool();
RHTTPConnectionInfo connInfo = iSession.ConnectionInfo();
connInfo.SetPropertyL ( strP.StringF(HTTP::EHttpSocketServ,
RHTTPSession::GetTable() ),

THTTPHdrVal (iSocketServ.Handle()) );
TInt connPtr = REINTERPRET_CAST(TInt, &(iConnection));
connInfo.SetPropertyL ( strP.StringF(HTTP::EHttpSocketConnection,
RHTTPSession::GetTable() ),
THTTPHdrVal (connPtr) );
if(errConnect!=KErrNone)
{

TBuf<100> errMsg;
errMsg.Copy(_L("Unable to connect to server."));
iObserver.ClientEvent(errMsg);
return;
}

iConnectionSetupDone = ETrue;

need help

thanks,
