The error you are getting seems to indicate that it can not resolve the
service you are trying to connect to, in your case, the NameService.
Without having tried out your code (what I have is incomplete), the way you
have specified the argv string seems a bit strange.  I assume that you are
trying to mimic the way command line options would be stored.  In that
case, I think it would be better to specify the options as follows:

  String[] argv={"-ORBInitRef",  
                 "NameService=corbaloc:iiop:192.168.1.28:8001/NameService"};

Again, I haven't been able to try this out since the code you have provided
is incomplete, but I think this is more what you are looking for.

You can also specify the NameService options through properties, which you 
are already using for two other properties.  In this case, you would be
trying to set the "ooc.orb.service.NameService" property.  See the manual
(Chapter 3) for more details on using these properties.

Darren
