Question

Could all those CORBA experts out there please help me with this one.

I have a multithreaded application with some code that sends a message to a server and waits for a response back. I can see that the server is sending the response back however the application doesnt seem to receive it.

Heres part of my code.

  // Create a request object for the given message
  msg.request = serverRef->_request("receiveCoreMessageVia");
  msg.request->set_return_type (CORBA::_tc_short);

  msg.request->add_in_arg() <<= msg.sourceGateway;
  msg.request->add_in_arg() <<= msg.octetSeq;

  msg.request->send_deferred();

  ...
  // The following code is in a while loop in a different function. It uses the request reference to check the response.
  // Check if the request has completed
  if (!msg->request->poll_response())
  {
    clssendlog << debug << "Polling..." << endl;

    return false; // No response yet
  }

  // Get the returned result
  clssendlog << debug << "Get response..." << endl;
  msg->request->get_response();

  clssendlog << debug << "Reading the returned response value" << endl;
  CORBA::Short tmp = 0;
  msg->request->return_value () >>= tmp;

The result is that it keeps saying Polling even if the server responds.
This is a basic DII invocation and I am actually testing the code on ACE/TAO 5.7.9. This exact code works perfectly on omniORB 4.1.4. However, I really want this to work on ACE/TAO.

Managed to fix by changing object reference from _ptr to _var. I wrote a small test application to verify this. After changing the pointer type its behaving as expected serving the responses. So the problem was getting the initial reference to the interface.
