Question

why I get a expected ';' before 'RegistrationHandler' in my code, cant find the error?

Q_DECL_EXPORT int main(int argc, char **argv)
{
    // this is where the server is started etc
    Application app(argc, argv);

    // localization support
    QTranslator translator;
    QString locale_string = QLocale().name();
    QString filename = QString( "MyApp_%1" ).arg( locale_string );
    if (translator.load(filename, "app/native/qm")) {
        app.installTranslator( &translator );
    }

    new MyApp(&app);

    const QString uuid(QLatin1String("abc"));
    RegistrationHandler *registrationHandler = new RegistrationHandler(uuid, &app);

    return Application::exec();
}

I re-indented your code, it was hard to read.

Please show how the declaration of RegistrationHandler works, there’s no #includes shown in this code and clearly it’s not declared in the included code, either.
