You might want to take a look at the mono project (its C#, supports CORBA,
and runs in linux) kill 3 birds with 1 stone.

Welcome.
I`m trying to prepere some project that shows how to use Corba technology
i heterogenic systems. I`d like to create CORBA server with Borland Delphi
(or C#.NET) and few client applications taht comunicate with serwer: J2ME
client for WindowsCE 5.0, c# or Delphi from WindowsXP, some Web
application using Java and maybe something for Linux system. For few days
i`m looking for some examples in internet but most of them using only one
of environment i`d like to use and don`t show how to use it with other.
and now i have few questions. Any help will be very good:
1. First step i`he tried to do was to obtain comunication between Delphi
CORBA Server (CosNaming example from DEMO\Corba folder in Delphi6) that
use VisiBroker ORB, and Java client using ORB from JSDK. Unfortunately i
doesn`t work for me.
I`ve made those steps:
* server and client use ILD definition like this:
interface Account {
float balance();
};
* run Visibroker Smart Agent on server side
* register Account object in VisiBroker Name Service: NameExtF Account
mylog.txt
* run server application
* when i`m using osfind.exe, i see registred Acount object:
osfind: Found one agent at port 14000
HOST: Tomek
* run java client application: java -classpath .
AccountClient -ORBInitialPort 14000 -ORBInitialHost Tomek
in client`s main function is:
ORB orb = ORB.init(args, null);
//!! NamingContext root =
NamingContextHelper.narrow(orb.resolve_initial_references("NameService"));
and in the second line (with !!) it crashes, i`m thingking it`s about
communication with VisiBroker NameService error I don`t know what`s going
on: when i`m trying to connect Delphi client to delhi server evertything
works fine, when i`m trying to connect from java client to java server
that use ORBD NameService evyrything works OK. when java and delphi should
cooperate - i`t doesn`t work :(.
Maybe you have some ideas what i`m doing wrong. Thanks for any. If you
have some working examples it will be very useful too.
I could use here C#.NET based CORBA server. Maybe it will be easier but i
don`t know what ORB use with C#.NET.
2. When comunication between Delphi (or C#) server and java client will be
working i`d like to implement other client application
and here i have few questions too:
- what ORB use with WindowsCE and J2ME. do you know openfusion jacorb will
be OK? Maybe you have some examples of using it to comunicate with
some server ORB
- what ORB use with C#.NET. Any examples will be very usefull.
- what ORB use from Linux and C++. Which distribution of Linux use. Any
example will be super.
About solutions it`s don`t important to work it quick and effective. Easy
solutions are best for me.
One more time i`m asking help. Thanks for any. Best Regards - gRabbi
