Pozdrav pokusavam da napravim corba client server aplikaciju u javi, radim na osnovu knjige "Teach Yourself CORBA in 14Days" samo sto je tamo koriscen Visibrocker a ja koristim javin idlj kompajler. U pitanju je StockMarket aplikacija. Napravio sam server i on radi bez problema ali imam problem sa klijentom, ovo je vec treca nedelja kako razbijam glavu. Startujem orbd servis, pa zatim i server i sve to radi a kad startujem klijent dobijam ovu gresku:

EROR: org.omg.CORBA.NO_IMPLEMENT: vmcid: 0x0 minog code: 0 completed:no
org.omg.CORBA.NO_IMPLEMENT: vmcid: 0x0 minog code: 0 completed:no
at com.sun.corba.se.internalcorba.ORBSingleton.resolv e_initial_references(ORBSingleton.java:290)
at StockClient.connect(StockClient.java:25)
at StockClient.main(StockClient.java:58)

at StockClient.connect(StockClient.java:25)
at StockClient.run(StockClient.java:14)
at StockClient.main(StockClient.java:59)

ovo je kod klijenta:

Code:

import StockMarket.*;
import org.omg.CosNaming.*;
import org.omg.CosNaming.NamingContextPackage.*;
import org.omg.CORBA.*;

public class StockClient {
    StockClient() {
    }

public void run() {

    connect();
    if (myStock != null) {
    doSomething();
    }

}

protected void connect() {
  try {
    ORB orb = ORB.init ();
    org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService") ;
    NamingContextExt  ncRef = NamingContextExtHelper.narrow(objRef);

    String name = "StockMarket";
    myStock = StockHelper.narrow(ncRef.resolve_str(name)) ;

    System.out.println("Obtained a handle on server object: " + myStock);
    System.out.println("Succesfully bound to a StockServer.");

         }
    catch (Exception e) {
    System.out.println("EROR : " + e) ;
    e.printStackTrace(System.out);
    }
}

protected void doSomething() {
try{
    String [] stockSymbols = myStock.getStockSymbols();
    for (int i = 0; i < stockSymbols.length; i++) {
           System.out.println(stockSymbols[i] + "  " + myStock.getStockValue (stockSymbols[i]));
    }
    }
    catch (org.omg.CORBA.SystemException ex) {
       System.err.println("Fatal eror: " + ex);
    }
    }

public static void main (String args []) {

    StockClient stockClient = new StockClient();
    stockClient.connect() ;
    stockClient.run();
    while (true);
    }

private Stock myStock;
}

zna li neko u cemu je problem?

Ukljucio bi jos neke biblioteke poput util.* i io.*.

A connect() bi ovako probao:

protected void connect() {
try {

String args[] = null;

ORB orb = ORB.init(args, null);

org.omg.CORBA.Object objRef =
orb.resolve_initial_references("NameService");

NamingContext ncRef = NamingContextHelper.narrow(objRef);

String name = "StockMarket";
myStock = StockHelper.narrow(ncRef.resolve_str(name)) ;

System.out.println("Obtained a handle on server object: " + myStock);
System.out.println("Succesfully bound to a StockServer.");

}
catch (Exception e) {
System.out.println("EROR : " + e) ;
e.printStackTrace(System.out);
}
}
