Developing a CORBA Client
Gopalan Suresh Raj

To work with any of these samples, you will need the following:
.........................................JDK 1.2 (Java 2)
The idltojava compiler

The Steps involved in developing a CORBA Client are:

  1. Implement your CORBA client application
  2. Compile the files and run the CORBA client

1. Implement your CORBA client application
 * StockMarketClient

import org.omg.CORBA.*;    
// All CORBA applications need these classes.
import org.omg.CosNaming.*;
// Client will use the naming service
import SimpleStocks.*;     
// The package containing our stubs.

public class StockMarketClient {
  public static void main(String[] args) {
    try {
// Create and initialize the ORB
      ORB orb = ORB.init(args, null);
// Get the root naming context
      NamingContext ncRef = NamingContextHelper.narrow(orb.resolve_initial_references("NameService"));

      // Resolve the object reference in naming
      NameComponent path[] = {new NameComponent("NASDAQ", "")};
      StockMarket market = StockMarketHelper.narrow(ncRef.resolve(path));

// Call the StockMarket server object and print results
      System.out.println("Price of MY COMPANY is $" + market.get_price("MY_COMPANY"));
    } catch( Exception e ) {

2. Compile the files and run the CORBA client

E:\MyProjects\corba\StockCorba>javac *.java

E:\MyProjects\corba\StockCorba>java StockMarketClient
Price of MY COMPANY is $159.2
