Attempting to connect to CORBA service using corbaloc url

    String[] orbargs= {};
    org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(orbargs, null);
    org.omg.CORBA.Object cobj = orb.string_to_object("corbaloc:iiop:10.1.1.200:6969/OurServiceHelper");
    _OurServiceHelper cpsh = _OurServiceHelperHelper.narrow(cobj); // Get stuck
    cpsh.ourMethod();

This narrow one just hangs.

My service is configured to work on a static port. And we know that this works, as we usually view it through the NamingService.

What am I doing wrong?

There is no type information in corbaloc, so the ORB checks the type you are narrowing down by making a remote call (_is_a). Try using an unchecked narrow one that won't call _is_a:

_OurServiceHelper cpsh = _OurServiceHelperHelper.narrow(cobj);

It is odd that calling _is_a does not return for you. I assume that unchecked_narrow will work (you will get a non-zero result), but the reference to the object will not work.
