Hi all,
First, I am quite new to CORBA world. I work under Linux RedHat-3.0,
with MICO-2.3.11 and JacORB-2.3.3.
I was asked to make some MICO-compiled servers (that already work fine
under MICO ORB) to work under JacORB, for advanced testing. Now, my
servers register correctly to JacORB's NamingService, but I cannot use
correctly JacORB's ImR!
So as to investigate more easily, I have tried to debug this problem on
localhost, using simpliest MICO clients. I ask them to resolve the
running (JacORB) NS and ImR. Following is the extract of my MICO client
code:
************************************************************************
*********************
// Retrieve ORB
CORBA::ORB_var orb= CORBA::ORB_init(argc, argv);
// For more debugging, list active objects
cout << "CPP: Listing all active CORBA objects:" << endl;
CORBA::ORB::ObjectIdList_ptr objList=
orb->list_initial_services();
if (objList)
for(unsigned int i=0; i<objList->length(); i++)
{
CORBA::ORB::ObjectId id= (*objList)[i];
cout << "CORBA Obj" << i+1 << ": " << id << endl;
}
cout << endl;
// Retrieve NS's IOR
CORBA::Object_var ns_obj=
orb->resolve_initial_references("NameService");
CosNaming::NamingContext_var nc=
CosNaming::NamingContext::_narrow(ns_obj);
cout << "IOR for resolved NS= ";
cout << orb->object_to_string(nc) << endl << endl;
// Retrieve ImR's IOR
CORBA::Object_var imr_obj=
orb->resolve_initial_references("ImplementationRepository");
CORBA::ImplRepository_var imr=
CORBA::ImplRepository::_narrow(imr_obj);
cout << "IOR for resolved ImR= ";
cout << orb->object_to_string(imr) << endl;
************************************************************************
*********************
And the client was launched with:
> /tmp/exe/Client -ORBInitRef
NameService=iioploc://localhost:$NS_PORT/NameService -ORBInitRef
ImplementationRepository=iioploc://localhost:$IMR_ENDPOINT/the_ImR/ImRPO
A/ImR
(For those who are familiar to JacORB's ImR, I am using an endpoint
which should requests to point at a defined port).
Now, the result of the execution of my client is coherent with my
initial server problem: I can retrieve NS IOR, but narrowing the ImR
fails!
Do you have any suggestion to explain this? I am using a wrong type as
return value for _narrow(imr_obj?)
Thanks a lot for your help!
Severin
