Call the method of a ejb??

Question

hi!
I get EJB refrence ,How can I call the method of it?(I use the stand-alone application client)
code:
import javax.naming.*;
//import javax.naming.InitialContext;
import javax.rmi.*;
import java.util.*;
//import hello.*;
public class jndi {
public static void main(String[] args) {
try {     
Hashtable env = new Hashtable();
     env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://localhost:3000");
     Context initctx = new InitialContext(env);
     Object objref = initctx.lookup("HelloEJB");
the method I want to call
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
Because it is the stand-alone .I can not to convert the objref:
HelloHome helloHome =(HelloHome)objref;
what can I do???

Answer 1

It still can work.
Tere is a ClassCastException.
And the the class name of the objref is "com.sun.corba.se.internal.iiop.CDRInputStream_1_0$1".
but my EJB is named HelloEJB.
Is the object which I want to call????
