ClassCastException running JDev Generated EJB Client

Question

Hi,
I'm trying to test a CMP entity bean I created by using the JDev903 generated TestClient class. First I run the EJB I want to test, then I attempt to run the Client class. I get a ClassCastException. The exception occurs on the call to PortableRemoteObject.
How do I get this to run? I'm not sure how to get past this exception. Is there something else I need to run? Is there something that needs to be set in a config file.
I kinda expected this to run outta da box.
package Samplecom.ngit.iis.cmedia.cmptest;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import com.ngit.iis.cmedia.cmptest.Tcmmtpic;
import com.ngit.iis.cmedia.cmptest.TcmmtpicHome;
import java.util.Collection;
import java.util.Iterator;
import javax.naming.NamingException;
public class TcmmtpicClient {
public static void main(String [] args) {
TcmmtpicClient tcmmtpicClient = new TcmmtpicClient();
try {
Context context = getInitialContext();
TcmmtpicHome tcmmtpicHome = (TcmmtpicHome)PortableRemoteObject.narrow(context.lookup("Tcmmtpic"), TcmmtpicHome.class); <=== EXCEPTION OCCURS HERE ===>
Tcmmtpic tcmmtpic;
// Retrieve all instances using the findAll() method
// (CMP Entity beans only)
Collection coll = tcmmtpicHome.findAll();
Iterator iter = coll.iterator();
while (iter.hasNext()) {
tcmmtpic = (Tcmmtpic)iter.next();
System.out.println("tpic_cmvg_id = " + tcmmtpic.getTpic_cmvg_id());
System.out.println("tpic_id = " + tcmmtpic.getTpic_id());
System.out.println("tpic_sequence_no = " + tcmmtpic.getTpic_sequence_no());
System.out.println("tpic_nm = " + tcmmtpic.getTpic_nm());
System.out.println();
} catch(Throwable ex) {
ex.printStackTrace();
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "ormi://localhost:23891/current-workspace-app");
return new InitialContext(env);
Thanks,

I was attempting to run this under JDev. I created a CMP from a table and then created the client to run it. I started the bean and then ran the client with the following result.
The stack trace is listed below.
