AW: [omniORB] OrbixWeb server answers OBJECT_NOT_EXIST while invo king

[Schmidmeier, Arno]

Hello Robert,=20
hello everybody,

Just at the beginning, what was the result of your chat with the
OrbixWeb-guys?

I run in the same problem with MICO, and verified that it is the same
problem with OmniORB.
However there is also a workaround in the Code of your working =
application.
Under some circumstances, it is sometimes just a reconfiguration issue =
of
the server application :-), if you are lucky, if not you might be lost. =
:-(

Based on the analysis of the orbixdj log file, I got the assumption =
that the
orbixdj is buggy.
So I my attempt was configure the server applications not to use the =
orbixdj
deamon.
(Drawback, You can only have persistant servers).

What I did, for the workaround is, I configured the server to use the
portnummer of the serverapplication and not the portnumber of the
orbixwebdeamon. The portnummer of the orbixwebdeamon is the deafault. =
Any
invocations are redirected to the real application from the orbixdj.=20

It seems to me, that it is the orbixdj, which is causing the problem.

Following code statements reconfigures the application, to use its own
portnumber in the IORs, and not the portnumber of the server =
application:
        ((IE.Iona.OrbixWeb.CORBA.ORB)
orb).setConfigItem("IT_IIOP_USE_LOCATOR","true");

The serverapplication must already know its portnumber before the =
invocation
of .        ((IE.Iona.OrbixWeb.CORBA.ORB)
orb).setConfigItem("IT_IIOP_USE_LOCATOR","true");

You could do it, with
IE.Iona.OrbixWeb.Features.Config.setConfigItem("IT_IIOP_LISTEN_PORT",Str=
ing.
valueOf(2004));
Both of these parameters can be defined via the commandline, or via the
orbixweb properties file
(till 3.1, I have not checked the update 3.2)=20

P.S.: I was never on the payroll of Iona, I have also no contracts with
Iona, except the license agreements. I have only the need to connect to
OrbixWeb-Server Applications.
