JNDI problem with Sun Application Server

Question

I am trying to call a extremely simple EJB from a remote computer. But everytime I run the client I get a Class castException. I have used Weblogic and Jboss in the past and I never had any problem with JNDI. I included all the files except for the descriptor. Please help, this is driving me nut.
Here is the exception i get:
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:293)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
at clients.testEjbTest.main(testEjbTest.java:42)
The remote Interface :
package ejb.test;
import javax.ejb.*;
public interface Test extends javax.ejb.EJBObject{
public String getResult() throws java.rmi.RemoteException;
The Home interface is:
package ejb.test;
import javax.ejb.*;
public interface TestHome extends javax.ejb.EJBHome{
public Test create() throws java.rmi.RemoteException, CreateException;
The Bean is:
package ejb.test;
import javax.ejb.*;
public class TestBean implements javax.ejb.SessionBean {
public TestBean() {}
public String getResult() { return "hello";}
public void ejbActivate() {  }
public void ejbPassivate() {  }
public void ejbRemove() {  }
public void ejbCreate() throws CreateException {  }
public void setSessionContext(javax.ejb.SessionContext sessionContext) { }
The client is:
public class testEjbTest {
public testEjbTest() { }
public static void main(String[] args) {
try{
Properties env = new Properties();
env.setProperty("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory" );
env.setProperty("java.naming.provider.url", "iiop://192.168.0.102:3700");
InitialContext ic = new InitialContext(env);
Object objref = ic.lookup("TestBean");
Object tt = PortableRemoteObject.narrow(objref, ejb.test.TestHome.class);
}catch(Exception e){e.printStackTrace();}

Hi,
I am new to this Forum.
I have an application running on Weblogic.
I want to shift to using SunOne as the Webserver and weblogic as application server.
But when I deploy the application I am getting this ClassCastException

protected LoginSession getLoginSession() throws ApplicationException {
LoginSessionHome home = null;
LoginSession object = null;
try {
home = (LoginSessionHome) (PortableRemoteObject.narrow(ProxyUtil.getEJBHome(getProperties().getProperty(DataCoreConstants.LOGIN_JNDI_NAME),getProperties()),LoginSessionHome.class));
object = home.create();
catch(ClassCastException cse){
cse.printStackTrace();
logger.error("Class Cast Exception is thrown while casting the Object to                      LoginSessionHome");
logger.error(cse);
throw new ApplicationException(ExceptionConstants.CLASS_CAST_EXCEPTION);
return object;
}Same method is running on weblogic without any problem�
Help needed urgently.

Neha.
