C client for EJB session bean interface

["bdubois" <Bart DuBois ua ac be>]

Hello all,

I'm trying to use Orbit (2.9.0) to create a C client for a J2EE
application.

Therefore, I generated the IDL files for the home and remote interface,
as well as some essential EJB exceptions (CreateException and
RemoteException) of the related session bean using rmic.

When I try to use orbit-idl-2 to generate sources for the generated IDL
files, the idl compiler indicates that it cannot handle the "valuetype"
concept, which is used in the IDL translation of the CreateException.

Therefore,
I would like to ask you whether any of you have experience with
accessing a J2EE application from C using Orbit. Do you know a way to
cope with the value-type problem?

I assume hat the C-language mapping for CORBA does not support value
types (yet?). Is there any way to work around this problem. In example,
is there a way to write an IDL translation of the EJB-exception classes
that do not rely on valuetype?

Kind regards,

PS: I received the following output from the orbit idl-compiler:

It's original java-declaration is:

    public CreateException(String message) {
        super(message);
    }
