JBoss 4.0.4.GA HomeHandle NoInitialContext
We use some kind of cache of HomeHandle objects in a remote JVM that obtains the Home object using the following code:
Hashtable environment = new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext context;
try {
context = new InitialContext(environment);
Object obj = context.lookup("ejb/EJBTest"); //ejb-name
EJBHome home = (EJBHome)PortableRemoteObject.narrow(obj,EJBTestHome.class); // (1)
...
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
After (1) we store the HomeHandle of the EJBHome object in that way we can use it in a latter time saving the overhead of the lookup opeartion. BUT we get the following error when we invoke getEJBHome() on the stored HomeHandle object.

Anyone know why it is not working ? Anyone knows if there is a problem using a remote client (that lives outside de Jboss JVM) that stores/retrieve the HomeHandle of an EJBHome object that resides in the JBoss JVM.
