Jaroslaw,

Assuming that you have a naming service running  from the command line like:
orbd -ORBInitialPort 1050 -ORBInitialHost yourHostname

You should be able to specify the  parameters:

-ORBInitialHost yourhost -ORBInitialPort 1050

in the Properties/Execution/Arguments field corresponding to your
program from within
NetBeans. (Just right click on the program node in the "Explorer" tree
to locate
the Properties dialog.) Also, make sure all your jar files are mounted
in the Explorer.
(Do you have an error message from your run?)

Here's a sample program that worked fine for me from within NetBeans
using JDK 1.4.2:

import java.util.Properties;
import org.omg.CORBA.ORB;
import org.omg.CORBA.Object;
import org.omg.CosNaming.NamingContext;
import org.omg.CosNaming.NamingContextExtHelper;

public class Test {
 
   public static void main(String[] args) {
     
       try {
         
           Properties props = System.getProperties();
           //props.put("org.omg.CORBA.ORBInitialPort","1050");
           //props.put("org.omg.CORBA.ORBInitialHost","yourhost");
           final ORB orb = ORB.init(args,props);
         
           String[] services = orb.list_initial_services();
           for (int i = 0; i < services.length; i++) {
               System.out.println(services[i]);
           }
         
           Object obj =
           
//orb.string_to_object("corbaloc:iiop:yourhost:1050/NameService");
           
//orb.string_to_object("corbaloc:iiop:1.0@yourMicoHost:9001/NameService");
// locate Mico NameService
           orb.resolve_initial_references("NameService");
           System.out.println(" naming object = " + obj);
         
           if (obj != null ) {
               NamingContext rootContext =
NamingContextExtHelper.narrow(obj);
               System.out.println(" naming object = " + rootContext);
               System.out.println(rootContext._non_existent());
           }
         
       } catch (Exception ex) {
           ex.printStackTrace();
       }
   }
}
