请大家帮我看看是什么原因出错？

[liuchengren]

public static void OpenServer(String[] args)
{
try{

// create and initialize the ORB
Properties props = new Properties();
props.put("org.omg.CORBA.ORBInitialHost", "127.0.0.1");
props.put("org.omg.CORBA.ORBInitialPort", "999");
ORB orb = ORB.init(args, props);

// get reference to rootpoa & activate the POAManager
POA rootpoa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
rootpoa.the_POAManager().activate();


// create servant and register it with the ORB
HelloImpl helloImpl = new HelloImpl();
helloImpl.setORB(orb);

// get object reference from the servant
org.omg.CORBA.Object ref = rootpoa.servant_to_reference(helloImpl);
Hello href = HelloHelper.narrow(ref);

// get the root naming context
ShowMessageBox(shell, "ddddddddddddd", "11");
//orb.resolve_initial_references("ServerApp");
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
//上面这句出错

// Use NamingContextExt which is part of the Interoperable
// Naming Service (INS) specification.
ShowMessageBox(shell, "ddddddddddddd", "11");
NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);


// bind the Object Reference in Naming
String name = "Hello";
NameComponent path[] = ncRef.to_name(name);
ncRef.rebind(path, href);

System.out.println("HelloServer ready and waiting ...");

// wait for invocations from clients
orb.run();
}

catch (Exception e) {
System.err.println("ERROR: " + e);
//e.printStackTrace(System.out);
}
}

很可能是你连接的参数不对，比如端口是不是999，还有连接参数的写法是不是正确，我用过，写法是：
String[] aryArgs = new String[3];
aryArgs[0] = "-ORBInitRef";
aryArgs[1] = "NameService=corbaloc::" + corbaIP + ":" + corbaPort + "/NameService";
aryArgs[2] = "-OAthread_per_request";
