[omniORB] JACOrb Server and OmniORB Client connection

[T. Le Flour]

Hi all,
I would like to access a JacORB server from an omniORB C++ client.
The current situation is the following :
. The JacORB server registers itself to omniNames. By looking the
name server content, it seems the registration works correctly.
. From the OmniORB client, I get the JacORB client reference via
Omninames. By looking to the server IOR, everything seems to be
correctly set(IP, Port , Type ID,...)
. When i want to narrow the object reference , i got the message :
omniORB: ERROR -- the application attempted to invoke an
operation on a nil reference. terminate called after throwing an
instance of 'CORBA::INV_OBJREF'

Are there some incompatibilities between the 2 ORB's implementations
(characters encoding, ...) or some specifics configurations to set?
Any ideas ?
Thanks in advance

Best regards.

That implies that you are using _narrow to narrow the object reference,
then you are immediately trying to invoke a method on it? Is that
right? If so, the problem is that the object does not have the expected
interface, so _narrow returns nil.

Perhaps JacORB and omniORB have a different view of the repository ids
of the interfaces?

Cheers,

Hi Duncan,
thank you for your answer. It is exactly what i am doing.
But, when i get the IOR from OmniNames(see below), i found all the
informations of the JacORB server.(even the interface name)
Does it mean that OmniORB and JacORb are nor inter-operable ?
Cheers,
Thierry

omniORB and JacORB interoperate fine. What exactly is the code that you
have on the omniORB side? Exactly which bit of it throws the INV_OBJREF
exception?

Post by T. Le Flour
Type ID: "IDL:Camera/AutoFocus:1.0"

Is that the repository ID that omniORB thinks the interface has?

Perhaps you could run the omniORB side with -ORBtraceLevel 30
-ORBtraceInvocations 1
