I understand the difference, I just used omniNames to test.
The client has no IOR. I suspect it uses Orbix' bind/_bind ("MyClass").
I've told it through its configuration file the host (10.2.1.30) and
port where to contact my server. That's why my server receives an
incoming connection, though the client has no IOR. The port I use for
my server is fixed by using -ORBpoa_iiop_port option.
I guess from there the client has to find a server-local object
identification for an object of class MyClass . That should be the
purpose of the LOCATE_REQUEST, if I interpret its name correctly; i.e.
it's not only to check the object's presence since the client does not
know yet who the object is.
Or is the string passed to LOCATE_REQUEST considered THE server-local
object identification ?
As for the error from the client, I only receive an application-level
message. Nothing technical to get from it. With a network sniffer
(ethereal) I see that omniORB returns MessageType=LocateReply,
When omniNames answered successfully I remember that this status was 1.
Seems it can't return any object identification, so you must be right
about the purpose of LOCATE_REQUEST.
Conclusion: the question seems to become: how do I declare an object
with a given name, such that LOCATE_REQUEST considers the name present
in the server.
Any more ideas ?
Thanks for help,
