[omniORB] using persistent reference with corbaloc

Hi Frederico,
unfortunately you do not write how you try to resolve your URI. You can use
the URI just like an ordinary stringified IOR and call string_to_object() on
it.
For your very first test I suggest to use the predefined 'omniINSPOA' on the
server side instead of a self-made one. You can even use it as your root
POA, so the code becomes quite simple.
Here is the echo example from the manual in a corbaloc variant. The only
different lines on the server side are the following (error handling
excluded):
// Get a reference to the omniINSPOA
CORBA::Object_var obj = orb->resolve_initial_references("omniINSPOA");
...
PortableServer::POA_var insPoa = PortableServer::POA::_narrow(obj);
...
// Create unique object key for IOR and activate with id
PortableServer::ObjectId_var echoOid =
PortableServer::string_to_ObjectId( "TheEcho" ); // Example name
insPoa->activate_object_with_id( echoOid, myecho );
...
Start the server with option "-ORBendPoint giop:tcp::40001".
On the client side you have:
// Convert stringified IOR to Object Reference
const char* sior = argv[1];
CORBA::Object_var obj = orb->string_to_object( sior );
Echo_var echoref = Echo::_narrow( obj );
...
Start the client with argument "corbaloc::localhost:40001/TheEcho"
Once this works you can try to make it more cumbersome... ;-)
