[omniORB] Using a corbaloc URI (JacORB client, omniORB server)

Thu Sep 5 20:08:01 2002

You can find all the answers in the docs, chapter 4.

In short, you should use the special POA for this: omniINSPOA:

Server:

     obj = orb->resolve_initial_references("omniINSPOA");
     PortableServer::POA_var poa = PortableServer::POA::_narrow(obj);
     PortableServer::POAManager_var pman = poa->the_POAManager();
     pman->activate();
     // Create object id (Always use the same one)
     PortableServer::ObjectId_var oid =
          PortableServer::string_to_ObjectId("HelloDemo");
     // Create the servant

     HelloDemoImpl* servant = new HelloDemoImpl();
     poa->activate_object_with_id(oid.in(), servant);
     servant->_remove_ref();
...

Also, you should run the server with the following command line parameters
-ORBpoa_iiop_port  <port>
where port 39537 in your case

And another thing, specify the protocol version in the URI (the default
value can be different for different ORBs):
corbaloc:iiop:1.0@myhost.mycompany.com:39537/HelloDemo

This seems like it should be simple, but I can't make it work.  What
I've got is a simple "hello world" type application with a JacORB client
and an omniORB server.  When I try to connect to the server using a
corbaloc I get an org.omg.CORBA.OBJECT_NOT_EXIST error.  I've tried
every possibility for the object key portion (which is where I suspect
the problem is), but nothing has worked.  Everything works fine if I use
the IOR, and also works using omniMapper.  Code snippets are below:

SERVER:

  CORBA::Object_var obj = orb->resolve_initial_references("RootPOA");
  PortableServer::POA_var rootPOA = PortableServer::POA::_narrow(obj);

  HelloDemoImpl* di = new HelloDemoImpl();

  PortableServer::ServantBase_var servant = di;
  PortableServer::ObjectId_var diid = rootPOA->activate_object(di);

-----------------------

CLIENT:

  ORB orb = ORB.init(args, null);

  org.omg.CORBA.Object obj =
orb.string_to_object("corbaloc::myhost.mycompany.com:39537/HelloDemo");

  HelloDemo hDemo = HelloDemoHelper.narrow(obj);

-----------------------

It fails on the narrow call.  Here is the output from the server running
with traceLevel of 30:

Any ideas?
