WebService cancelling problem

[nadav70]

Hi,

I have used the wsdl2cpp tool to create a Web Service class.
I'm calling the generated class's asynchronous method. It works fine when server replies and when server refuses connection.

Problem starts when server doesn't reply at all (timeout). In this case I never get a response. So I've placed a timer, and when it pops up, I'm deleting the generated class. Then the generated class gets stuck when its destructor tries to delete the CSenServiceConnection member:

CLoginConnectService::~CLoginConnectService()
{
    if (iOwnsConnection)
    {
    	delete iConnection; // <== This line never returns
    }    
    Xsd::SenOps::DestroySanyi();
}

I've tried also calling iConnection->Cancel() before deleting, but then it gets stuck on the Cancel() line:

CLoginConnectService::~CLoginConnectService()
{
    if (iOwnsConnection)
    {
    	iConnection->Cancel(); // <== This line never returns
    	delete iConnection;
    }    
    Xsd::SenOps::DestroySanyi();
}

Also tried calling iConnection->TransactionCompleted(), but this got stuck too:

CLoginConnectService::~CLoginConnectService()
{
    if (iOwnsConnection)
    {
    	iConnection->TransactionCompleted(); // <== This line never returns
    	delete iConnection;
    }    
    Xsd::SenOps::DestroySanyi();
}

Can this be fixed?

Thanks,
Nadav

Guys, anyone knows the answer? There must be one, because this is so basic. Surely Nokia wouldn't have published a communication package that cannot handle timeout, right?

Bump. I have same problem.

Bump. I have same problem.

Hi Niko,

The only way I've managed to solve it was to implement WebServices myself. I've written a macro-based infrastructure that instead of automatically using the WSDL, requires the user to define the WebService in a special header file. The infrastructure then defines the required classes, and takes care of serialization, deserialization and transport (which uses an asynchronous method).

Cheers,

And one thing more:

Eventually, we've decided not to use WebServices, because it is very wasteful (it sends a lot of overhead data). Still I have the infrastructure, so if you like it, you can leave me an email and I will send you the source code.

Cheers,
Nadav

Nadav,

As we spoke, i am having this exact problem, but i realized that only happens in one of my phones: E61. Somehow i dont get any of these problems with other devices or the emulator.

I tried to catch the error with a HandleError in my GUI, and nothing, no error, just hanging there...waiting for the connection to be closed/deleted.

I aslo met the same problem

when I cancel the iConnection,it still send a message to the Server,how do you solve this problem? My email is s3922731@126.com
