Client calling EJB + No object bound eror

Question

Hi,
I am a newbie to oc4j. I have tried to get a client to call a stateless ejb using a bat file outside the server, with no luck. I get NamingException: No object bound for java:comp/env/EmployeeBean when doing a jndi lookup. I have read the doc's, tried the answers in the forum and I even used the example code provided from oracle, but I still get the same error message every time.
Has anyone come across this issue when calling an ejb from a client??
Any help would be greatly appreciated. It’s driving me crazy.
Thanks
David

Hi,
I will check out the link, thank you. I am a newbie to java and oracle, so any help would be great. i wasnt sure which bits of code would be really helpfull, so i just put most of it in, sorry if it is too much info.
i am using oracle9ias release 1.0.2.2a (i dont know if this would make any difference). I deploy all my ears using the enterprise manager. The client-jar is within the ear. i use a bat to run the Client code.
I can get a servlet to call the same ejbs and that works fine.
#batfile
========
i set the classpath which including refernces to oc4j.jar and oc4jclient.jar and my ejb-jar
and then i use
set BigD=-Dorg.omg.CORBA.ORBInitialHost=localhost -Duser.timezone=ECT
java.exe %BigD% -classpath "%classpath%" com.test.client.Client
//Client Code
=============
public class Client {
     public static void main(String[] args) {
          System.out.println("Client started again...");
          try {
               Context context = new InitialContext();
               System.out.println("got context");
               Object homeObject = context.lookup("java:comp/env/ejb/ConsumerRequestSession");
               ConsumerRequestSessionHome home = (ConsumerRequestSessionHome) PortableRemoteObject.narrow(homeObject, ConsumerRequestSessionHome.class);
               System.out.println("got home");
               ConsumerRequestSession remote = (ConsumerRequestSession) PortableRemoteObject.narrow(home.create(), ConsumerRequestSession.class);
               System.out.println("got remote");
               String retValue = remote.getString();
               System.out.println("The retValue from client is : " + retValue);
          }catch(Exception e) {
               e.printStackTrace();
               System.out.println("ERROR in try block of client when creating jndi :" + e.getMessage());
