[omniORB] RootPOA and omniINSPOA together

[Urban Purkat]

Hi!

I am working on openarchive project (http://www.openarchive.net/).
The product uses omniORB for its IPC library with connection to 
omniNames service.
It currently uses "RootPOA" and it works fine for communication within 
one openarchive system.

I would like to connect two systems. Therefore the first system needs to 
connect to the second system's name service (NS2) to resolve objects. 
Since omniORB does not allow me to have multiple orb instances this is 
not doable.
I thought I can implement fixed references for some servants and resolve 
objects from a predefined string.
In order to do that I introduced a secondary POA (omniINSPOA).

Here's a code snippet where I initialize omniORB:
m_orb = CORBA::ORB_init(a_argc, a_argv, s_orbName, options);
obj = m_orb->resolve_initial_references("RootPOA");
m_poa = PortableServer::POA::_narrow(obj);

// New code
obj = m_orb->resolve_initial_references("omniINSPOA");
m_poa2 = PortableServer::POA::_narrow(obj);
// New code end

obj = m_orb->resolve_initial_references("NameService");
m_rootContext = CosNaming::NamingContext::_narrow(obj);

After that I am ready to resolve objects from NS.
Note: The endPoint parameter is not set.

In management interface process (MIF) servant constructor I register to 
naming service and additionally also activate servant using ID:

string objectName("mif");
PortableServer::ObjectId_var oid =
    PortableServer::string_to_ObjectId(objectName.c_str());
m_poa2->activate_object_with_id(oid, this);    

In order to be able to resolve this object from another process using a 
fixed object name I need to set the endPoint parameter to 
giop:tcp:ivd-test-01.topit.si:2809.
After I set it I cannot resolve any object using NS. But If I leave port 
empty (giop:tcp:ivd-test-01.topit.si:) NS resolution is successful, but 
I cannot narrow fixed object using the following code:
string objectUri = string("corbaloc:iiop:") + m_hostname + 
string(":2809/mif");
CORBA::Object_var obj = m_orb->string_to_object(objectUri.c_str());

i_ManagementInterface_var mif = i_ManagementInterface::_narrow(obj);

Here's trace:

omniORB: omniRemoteIdentity deleted.

The omniORB configuration can be found at the end of mail.

Can both POAs be used together?
If no, do you have any other ideas how to connect to the other system?
I would really appreciate some help.

Urban
