How to add an object to node by using AdminPrx?

[Jiangyubao]

Hi, all.

I want to deploy applications to servers shown as attachment(ServerTopLogic.png).

I startup icegridregistry and icegridnode at my Linux operating system, and I want to add an object to it, so write the following code:

package Demo.main;

import Demo.impl.HelloImpl;
import Ice.ObjectAdapter;

public class AddObject extends Ice.Application {
	public int run(String[] args) {
		try {
			IceGrid.RegistryPrx registry = IceGrid.RegistryPrxHelper
					.checkedCast(communicator().stringToProxy(
							"DemoIceGrid/Registry"));
			IceGrid.AdminSessionPrx session = registry.createAdminSession(
					"foo", "bar");
			IceGrid.AdminPrx admin = session.getAdmin();
			ObjectAdapter adapter = communicator().createObjectAdapter(
					"HelloAdapter");
			Ice.Identity ident = communicator().stringToIdentity("HelloObject");
			Ice.ObjectPrx factory = adapter.add(new HelloImpl(), ident);
			try {
				admin.addObject(factory);
			} catch (IceGrid.ObjectExistsException e) {
				admin.updateObject(factory);
			}

		} catch (Exception e) {
			e.printStackTrace();
		}
		return 0;
	}

	public static void main(String[] args) {
		AddObject app = new AddObject();
		int status = app.main("Admin", args, "client.cfg");
		System.exit(status);
	}
}

But the program can't work, and the error message is:

Ice.InitializationException
    reason = "object adapter "HelloAdapter" requires configuration."
	at Ice.ObjectAdapterI.<init>(ObjectAdapterI.java:789)
	at IceInternal.ObjectAdapterFactory.createObjectAdapter(ObjectAdapterFactory.java:183)
	at Ice.CommunicatorI.createObjectAdapter(CommunicatorI.java:71)
	at Demo.main.AddObject.run(AddObject.java:15)
	at Ice.Application.main(Application.java:114)
	at Ice.Application.main(Application.java:57)
	at Demo.main.AddObject.main(AddObject.java:33)

What is the problem?
