OmniOrb and Orocos script language

Hi all,
I'm trying to understand how to use omniORB to use the .ops scripts...

I have a server (also DNS), called "caronte", where I lunched
"/etc/init.d/omniorb4-nameserver start"

On a client, I made a file like:

--------testPhantomCorba.ops----------

import("sensPhantom")
loadComponent("SensPhantom","SensPhantom")
loadComponent("SensPhantom.ior","IORFile")
loadComponent("IOR:.....", "IOR")

following some documentation but:

1.What I need to put into .ior file?
2.Where I can find this IOR?
3.what's the correct command line? (deployer-corba-gnulinux -s
testPhantomCorba.ops?)

Thanks,
Fabrizio
