Example of CORBA () -------- I don't know what it is :-)

Below is a simple example of a CORBA program
Download the source file
1. produce a idl file like this
Hello. idl
Module HelloApp {
Interface Hello {
String sayHello ();
};
};
2. produce stub and skeleton files through idltojava.exe
Idltojava hello. idl
Idltojava is not include in the jdk. But you can download it from idldojava.
3. write a server program like this
// HelloServer. java
Import HelloApp .*;
Import org. omg. CosNaming .*;
Import org. omg. CosNaming. NamingContextPackage .*;
Import org. omg. CORBA .*;
Import java. io .*;
Class HelloServant extends _ HelloImplBase
{
Public String sayHello ()
    {
Return "Hello world !! ";
    }
}
Public class HelloServer {
Public static void main (String args [])
    {
Try {
// Create and initialize the ORB
ORB orb = ORB. init (args, null );
// Create servant and register it with the ORB
HelloServant helloRef = new HelloServant ();
Orb. connect (helloRef );
// Get the root naming context
Org. omg. CORBA. Object objRef =
Orb. resolve_initial_references ("NameService ");
NamingContext ncRef = NamingContextHelper. narrow (objRef );
