But what I want is to use the CORBA specification COSNaming to ensure maximum portability and I seem not able to find it.

In my code I use

import org.omg.CORBA.*;

import org.omg.CosNaming.*;

import org.omg.CosNaming.NamingContextPackage.*;

public class EasyNaming {

private static NamingContext rootContext;

public static void main(String[] args) {

try {

org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args,null);


System.out.println("Initial services: ");

String[] services = orb.list_initial_services();

System.out.println(services.length);

for(int i = 0; i < services.length; i++)

System.out.println(services[i]);

org.omg.CORBA.Object obj = orb.resolve_initial_references("NameService");

rootContext = org.omg.CosNaming.NamingContextHelper.narrow(obj);

if (rootContext == null)
System.out.println("Cannot find Name Service!");

else System.out.println("Found NameService!");

} catch
(org.omg.CORBA.ORBPackage.InvalidName inex) {

System.out.println(inex);

} catch(org.omg.CORBA.SystemException corba_exception) {

System.out.println(corba_exception);

} }

}

But the above failed! Anyone knows how to activate this COSNaming service besides using VisiBroker vbj to start COSNaming service?
