Problems with NameService

I am new to Corba and i am trying to run my sample program in Corba using Jbuilder.
While trying to run the server I tried to get the name service but repeatedly i get the org.omg.Corba.COMM_Failure.
I am providing the code to the server and as well as the trace for further information
Note: i also tried using the NamingContext and NamingContextExt

public class CountServer {
public CountServer() {
public static void main(String args[]){
try {
ORB orb = ORB.init(args, null);
POA rootPOA = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
CountImpl cImpl = new CountImpl();
org.omg.CORBA.Object ref = rootPOA.servant_to_reference(cImpl);
count cnt = countHelper.narrow(ref);
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");Line Number 34
NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);
NameComponent nc = new NameComponent("count","");
NameComponent path[] = {nc};
System.out.println("Count Server is ready and waiting");
} catch (org.omg.CORBA.SystemException se) {
}catch(Exception e){

Server Trace:

org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No

Any help would be appreciated.
