    Simple CORBA java server

    This code shows an example of simple corba server in java. A CORBA server needs a local ORB object. The server instantiates an ORB and registers its servant objects so that the ORB can find the server when it receives an invocation for it. the server is a process that instantiates one or more servant objects. Each servant implements the
    // The package containing our stubs.
    import HelloApp.*;
    
    // HelloServer will use the naming service.
    import org.omg.CosNaming.*;
    
    // The package containing special exceptions thrown by the name service.
    import org.omg.CosNaming.NamingContextPackage.*;
    
    // All CORBA applications need these classes.
    import org.omg.CORBA.*;
    
    public class HelloServer 
    {
      public static void main(String args[])
      {
        try{
           // Create and initialize the ORB
          ORB orb = ORB.init(args, null);
          
          // Create the 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);
          
          // Bind the object reference in naming
          NameComponent nc = new NameComponent("Hello", "");
          NameComponent path[] = {nc};
          ncRef.rebind(path, helloRef);

          synchronized(sync){
            sync.wait();
