CORBA Client

I am relatively new with CORBA, most of my experience comes from
relating it to J2EE.  I am attempting to connect to a third party vendor
via their CORBA server.

I need to run the client on my iSeries running v5r2m0.  I cannot get a
connection.

Here is the snippet that attempts to initialize the ORB:

....

String instanceName = "something";
String [] corbaArgs = null;

Properties props = new Properties();
props.put("org.omg.CORBA.ORBInitialHost", "vendor.remote.ip");
props.put("org.omg.CORBA.ORBInitialPort", "someport");

System.out.println("Initializing the ORB");
ORB orb = ORB.init(corbaArgs, props);
                
System.out.println("Resolving reference to NameService");
Object objRef = orb.resolve_initial_references("NameService");
         
System.out.println("Narrowing NameService");
NamingContext ncRef = NamingContextHelper.narrow(objRef);
System.out.println("Naming context object is: " + ncRef);
                
System.out.println("Creating name component for " + instanceName);
NameComponent nc = new NameComponent(instanceName, "");


....



When I run it from qsh I get:


Initializing the ORB

Can anybody offer any assistance, with my limited CORBA experience I
have exhausted my resources.


Thanks,
