[omniORB] Re: omniORB3 problem?

[David Riddoch]

Hi Mark,


The mapping for the signature of object implementations has changed
between CORBA 2.0 and 2.3.  See page 103 of the c++ spec.  It basically
says that T_out types should be used as the parameter type for the out
arguments.

Thus you implementation signature should be:

  void work(Hammer_out obj);

(nb. I am assuming 'create' below should have been 'work')

_CORBA_ObjRef_OUT_arg<_objref_Hammer,Hammer_Helper> is just an omniORB
specific name for the same type.  You should use Hammer_out.

If you wish you can continue to use the old mapping, by passing the
-Bold_signatures option to omniidl3.


Cheers,
David
