Hi all,

I am trying to use a valuetype together with CORBAscript 1.3.5 and MICO 2.3.9.

My IDL looks like this:

   valuetype IChiVariable {

     // initializer

     factory init(in any value);

   };

   valuetype IChiVariableInt : IChiVariable {

     public long value;

   };

The implementation is done in CORBAscript:

   # valuetype class for IChiVariableInt

   class ICHIVARIABLEINT

   {

     proc __ICHIVARIABLEINT__(self) {}

     proc init(self, value) {

       self.value = value

     }

   }

   # register valuetype factory

   CORBA.ORB.register_value_factory("IDL:IChiVariableInt:1.0", ICHIVARIABLEINT)

When I execute the script, I catch the exeception “< NotFound: method ‘register_value_factory’ in scope ORB >”,

although the CORBAscript documentation specifies the ‘register_value_factory()’ method to be available.

On the other hand, basic ORB methods do work correctly, e.g.  “println( CORBA.ORB.list_initial_services() )”

correctly gives me the following list:

["DynAnyFactory", "ImplementationRepository", "InterfaceRepository", "RootPOA", "POACurrent", "PrincipalCurrent", "CodecFactory", "PICurrent"]

Anybody has an idea of what I am doing wrong?

Thank you very much and my best regards,

Michael

Hi,

I am just getting started using mico and unfortunately facing some frustrating beginner problems. I am trying to setup a simple client server Communication. The client offers some callbacks, which it registers at the Server. There are plenty tutorials on this, but none of them explains the following:

1. Does the client need a POA?

2. Does the client orb needs to run() ?

3. Do I need to start any services of the orb for this notification / subscriber mechanism?

I’ve created a callback object on the client and sent it to the server. The server invokes a method from that callbackobject. But the message never reaches the client. So I was wondering, what the client needs to accept messages from the server.

Thanks for any help. I was looking for a solution on the internet for a week. So I hope this beginner problem might be solved here.

Greetings

Clemens
