C# exception help

chang

I have a class Subscriber
class Subscriber : Ice.Application
{
...
}
in run method, I try to initial communicator and proxy, but the
communicator().createObjectAdapter("test.Subscriber"); failed.

The code looks like below
///////////////////////////////////////////////////
Subscriber sub = new Subscriber()
sub.main(args, "c:\\Config.sub");
...
//code initial m_communicator, (successl)
//code creates and objectProxy and TopicManagerProxy are success
...
//line causes exeption

m_ObjectAdapter = m_communicator.createObjectAdapter("test.Subscriber");

c:\config.sub file looks like below
TopicManager.Proxy=IceStorm/TopicManager:default -h 127.0.0.1 -p 10000
test.Subscriber.Endpoints=tcp:udp

Hi,

The debug stack trace doesn't show the reason of the failure which is in theory embedded with the Ice.InitializationException. Do you have the PDB installed next to the Ice assemblies or registered with the GAC (see here for more information on using the .NET Ice assemblies)?

The exception should contain the reason of the failure if you print it out:

try
{
    m_ObjectAdapter = m_communicator.createObjectAdapter("test.Subscriber"); 
}
catch(Ice.InitializationException ex)
{
     System.Console.Out.WriteLine(ex);
}

Most likely, it's a configuration problem and the test.Subscriber.Endpoints property isn't being correctly read. I noticed an extra space in the name of the adapter passed to m_communicator.createObjectAdapter, is it a typo in your code or just a copy/paste problem?

Cheers,
Benoit.

The extra space is paste problem. Some how ZeroC forum alwasy insert a space into it.

I will try you suggestion to figure it out.

BTW, since Ice.Application is design for console. I can not use it for win form application, right? Because of the thread safe issue?

Hi Chang,

In your first post, createObjectAdapter was raising an exception (Ice.InitializationException). In your second post, your program is apparently going further and raising Ice.ObjectAdapterDeactivatedException when you call add on your object adapter.

ObjectAdapterDeactivationException is raised, as its name indicates, when the object adapter is deactivated; you would typically deactivate your object adapter by shutting down its communicator.

Best regards,
Bernard
