[omniORB] omniORB's ORB::init(..) method.

[Ben Miller]

Even stranger: after giving the error "CORBA::ORB_init failed -- the
ORBid () is not omniORB3", the ORB_init method seems to have returned
a valid ORB reference anyway!  The return value does not return true
from CORBA::is_nil() and allows the code to go and
'list_initial_services()' correctly!

Any thoughts?

Ben.

Also, according to Henning & Vinoski (Client-Side C++ Mapping 7.8: ORB
Initialization) the third parameter to ORB_init should default to the
empty string.  If this is part of the mapping spec omniORB3 doesn't
comply as it won't compile

CORBA::ORB orb = CORBA::ORB_init(argc, argv);

??

Confused,
Ben.

Hmm, if I pass an empty string ("") as the third parameter like this:

CORBA::ORB orb = CORBA::ORB_init(argc, argv, "");

I get the runtime error:

CORBA::ORB_init failed -- the ORBid () is not omniORB3

But if I use:

CORBA::ORB orb = CORBA::ORB_init(argc, argv, 0);

everything works fine.  Is this correct?

Best regards,
Ben.

Just miss out the last parameter to ORB_init(), or pass an empty
string (not zero). That should work with all ORBs.

-ORBid should override whatever you pass as the third parameter. If is
failing to do that for you?

Cheers,

Duncan.
