Hi,

Can you run the application with -ORBDebugLevel 10? Are both programs TAO or
are you also using another ORB?

Hi there,

after some struggling, I managed to get a running deployment.
The reason it didn't work seemed to be some problems with .so dependencies.

However, I've got some problems with the next step: 

I have a running component, called CLoggerClient, which has the following
interface:

interface ILogAMessage
{
  void logthis (
      in string message
    );
};

component CLoggerClient supports ILogAMessage 
{
  uses ILogger logger;

  attribute long cycleTime;
  attribute string cyclicMessage;
};

I implemented a small executable, according to the starter in the Hello
example,
which just calls to method LogAMessage::logthis () on the CLoggerClient. 

Here is the corresponding code snippet:

      CORBA::Object_var obj =
        orb->string_to_object (loggerclient_ior);

      // narrow to a reference of the CLoggerClient component
      CLoggerClient_var loggerclient = CLoggerClient::_narrow ( obj.in ());

      if (CORBA::is_nil (loggerclient.in ()))
        {
          ACE_ERROR_RETURN ((LM_ERROR,
                             "Unable to acquire LoggerClient's objref\n"), 
                            -1);
        }

      loggerclient->logthis (CORBA::string_dup (logmessage));

However, the last call fails with the following output:

(20395|182924465856) EXCEPTION, Unknown exception 

system exception, ID 'IDL:omg.org/CORBA/COMM_FAILURE:1.0'
TAO exception, minor code = 6 (failed to recv request response; ENOENT),
completed = MAYBE

Uncaught CORBA exception

The CLoggerClient also gives some info, what happens:

If I understand this correctly, there is something going wrong on a rather
low level,
because the component cannot decode the request from the executable,
according to the message:
TAO (20208|182956442240) - Transport[9]::handle_input, error parsing
incoming message 

Do you have any advice, where I should start from to narrow down the
failure?

Thanks,
Friedhelm

Bad juju right here, you should be using gnuace instead of make.
