[omniNotify] resolving Notification Service

[Andy Goetz]

Hi,

I am new to omniNotify so please be patient if my question has an obvious
answer.

I am trying to get a VERY simple example working with a server and client
for omniNotify building them from scratch. I have hacked the examples code
to send my own events but I do not find it very clear. I would like to
write a server and client from scratch using the COS Notification API
directly. My first example fails just trying to get the
EventChannelFactory.

My code to get a handle on the EventChannelFactory looks like this :

    CosNotifyChannelAdmin::EventChannel_var eventChannelFactory;
    try
    {
        CORBA::Object_var obj =
            orb -> resolve_initial_references("NotificationService");
 
        //
        // Narrow the CORBA_Object reference to an EventChannelFactory
        // reference so we can invoke its methods
        //
        eventChannelFactory =
            CosNotifyChannelAdmin::EventChannelFactory::_narrow(obj);
 
    }
    catch(...)
    {
        cerr << "Cannot resolve `NotificationService'" << endl;
        exit(1);
    }
 
    //
    // Make sure the CORBA object was really an EventChannelFactory
    //
    if(CORBA::is_nil(eventChannelFactory))
    {
        cerr << "`NotificationService' initial reference is not "
             << "a CosNotifyChannelAdmin::EventChannelFactory"
             << endl;
        exit(1);
    }

But it never resolves the EventChannelFactory. I have tried resolving the
IOR in the /tmp/rdifact.ior file as well but when I do the narrow it says
this is not an EventChannelFactory.

My questions are :

(1) is the bootstrap method via "NotificationService" supported ?

(2) why can I not narrow /tmp/rdifact.ior to
    
    CosNotifyChannelAdmin::EventChannelFactory ?

Thanks for any help you can give on this.
