I still didn't solve my problem but I tried to deploy it on my local machine and see I could somehow find what the issue is when deploying it on a remote machine.

Initially deploying it on my local machine everything worked fine
However when I add the following line I see that code breaks.

  | String host = "jnp://localhost:1099"; 
  | props.setProperty(Context.PROVIDER_URL, host);
  | I started getting the following exception 
  | 2006-11-03 10:17:18,319 ERROR [STDERR] java.lang.ClassCastException
  | 2006-11-03 10:17:18,319 ERROR [STDERR] 	at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229)
  | 2006-11-03 10:17:18,319 ERROR [STDERR] 	at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
As soon as I uncomment that props.setProperty(Context.PROVIDER_URL, host);
line everything works fine.  
I have seen this type of exception before when I tried invoking the ejb on a different computer as well.  I am not sure how to see what is the wrapper class for the object since the call to object.getClass().getName() prints something like this $Proxy184

This is my code again:

Properties props = new Properties();

		props.setProperty(Context.SECURITY_PRINCIPAL, "admin");
		props.setProperty(Context.SECURITY_CREDENTIALS, "admin");
		props.put(javax.naming.Context.URL_PKG_PREFIXES,  "org.jboss.naming:org.jnp.interfaces");

		String host = "jnp://localhost:1099";
		props.setProperty(Context.PROVIDER_URL, host);
ctx = new InitialContext( props );

	Object object = ctx.lookup( "ejb/com/blah/Manager" );
		ManagerRemoteHome home = (ManagerRemoteHome)PortableRemoteObject.narrow ( object, ManagerRemoteHome.class);
		ManagerRemote manager = home.create();
