IceStorm and Services inside a IceGrid

Hello, I'm a new Ice User, and I'm trying to develop an application (Server and Cilent) where I would have 1 Service (HelloService) that expone a function 'Hello', and a Thread that publish on a IceStorm Topic the current time every second.

Server Side, I have written the code in C++, and I'm trying to develop the client in Java.

I start IceGrid with this cfg file:

IceGrid.InstanceName=AtsGrid
Ice.Default.Locator=AtsGrid/Locator:default -p 4061
IceStorm.TopicManager.Proxy=IceStorm/TopicManager
IceGrid.Registry.DefaultTemplates=C:\Program Files\ZeroC\Ice-3.4.1\config\templates.xml
IceGrid.Registry.Client.Endpoints=default -p 4061
IceGrid.Registry.Server.Endpoints=default
IceGrid.Registry.Internal.Endpoints=default
IceGrid.Registry.Data=db/registry
IceGrid.Registry.PermissionsVerifier=AtsGrid/NullPermissionsVerifier
IceGrid.Registry.AdminPermissionsVerifier=AtsGrid/NullPermissionsVerifier
IceGrid.Registry.SSLPermissionsVerifier=AtsGrid/NullSSLPermissionsVerifier
IceGrid.Registry.AdminSSLPermissionsVerifier=AtsGrid/NullSSLPermissionsVerifier

IceGrid.Node.Name=node1
IceGrid.Node.Endpoints=default
IceGrid.Node.Data=db/node
IceGrid.Node.CollocateRegistry=1

IceGrid.Node.Trace.Activator=1

IceGridAdmin.Username=foo
IceGridAdmin.Password=bar

After I have registered this application.xml:

<icegrid>

  <application name="Simple" import-default-templates="true">

    <node name="node1">

      <server-instance template="IceStorm" instance-name="IceStorm"/>

      <server id="SimpleServer" exe=".\bind\server_prova" activation="always">
        <adapter name="Hello" endpoints="tcp">
          <object identity="hello" type="::Demo::Hello" property="Identity"/>
        </adapter>
        <adapter name="Clock" endpoints="tcp">
          <object identity="clock" type="::Demo::Clock" property="Identity"/>
        </adapter>
      </server>
    </node>

  </application>

</icegrid>

Where Demo::Hello is the service, and Demo::Clock is the Topic Publisher.

Until here, Everything appear to work correctly:

C:\Project\atsGrid\cpp\atsNode>icegridnode --Ice.Config=grid.cfg
-- 11/02/11 17:39:20.048 icegridnode: Activator: activating server `SimpleServer'
-- 11/02/11 17:39:20.095 icegridnode: Activator: activating server `IceStorm'

Just pubblished : 11/02/11 17:39:24.385
Just pubblished : 11/02/11 17:39:25.399

But now, I can't subscribe the IceStorm Topic from My Java code:
This is my configuration:

Ice.Default.Locator=AtsGrid/Locator:default -p 4061
IceStorm.TopicManager.Proxy=IceStorm/TopicManager

This is the subscriber code

String topicName = "time";
String option = "None";
boolean batch = false;
String id = null;
String retryCount = null;
int i;
        
if(batch && (option.equals("Twoway") || option.equals("Ordered")))
{
    System.err.println(appName() + ": batch can only be set with oneway or datagram");
    return 1;
}

IceStorm.TopicManagerPrx manager = IceStorm.TopicManagerPrxHelper.checkedCast(
            communicator().stringToProxy("IceStorm/TopicManager"));
if(manager == null)
{
    System.err.println("invalid proxy");
    return 1;
}

try
{
    topic = manager.retrieve(topicName);
}
catch(IceStorm.NoSuchTopic e)
{
    try
    {
       topic = manager.create(topicName);
    }
    catch(IceStorm.TopicExists ex)
    {
        System.err.println(appName() + ": temporary failure, try again.");
         return 1;
    }
}
        
        
adapter = communicator().createObjectAdapter("Clock.Subscriber");

When I call communicator().createObjectAdapter I Get this Exception:

Ice.InitializationException
reason = "object adapter `Clock.Subscriber' requires configuration"

Any ideas?

Thanks!
