[omniORB] RE: Orbix to OmniORB integration problem

[David Riddoch]

Yan,


I think the problem may be with the Orbix object_to_string and
string_to_object methods.  Orbix has a proprietary format for stringified
IORs, which contains the host name.  You'll need to persuade Orbix to give
you a standard stringified IOR.  I think the following may work:

stringified_ior = 
  objref->_object_to_string(CORBA::IT_INTEROPERABLE_OR_KIND);

and something similar for string_to_object.

I got this from:

Hope this helps,
David
