Unable to locate Home Interface in WSS 3.5 AE

[Joel McNary]

I am attempting to create a client application using Websphere Advanced Edition 3.5. However, when I try to test it against the Websphere Server, I receive the following output/error message:
properties for Initial Context = {java.naming.factory.initial=com.ibm.ejs.ns.jndi.CNInitialContextFactory, java.naming.provider.url=iiop://172.16.200.201:900}

The code that generates this message is:

/**
 * Initialize the target home
 **/
private EJBHome lookupTargetHome(String jndiName, Class homeClass) throws NamingException {
//Get the PROVIDER_URL and the INITIAL_CONTEXT_FACTORY from the properties file
javax.naming.InitialContext initialContext = getInitialContext();
java.lang.Object obj = initialContext.lookup(jndiName);
System.out.println("Appempting to narrow object of class " +obj.getClass().getName()+" to EJBHome class " + homeClass.getName());
EJBHome home = (EJBHome) javax.rmi.PortableRemoteObject.narrow(obj, homeClass);
return home;
}

Why does the JNDI lookup return an IBM anonymous inner class when it should return an instance of the Home Class? What am I doing wrong that would cause this error?
