Returning remote reference

Question

Hi everybody, I'm having quite some trouble with RMI, everytime I try to return a reference to a Remote object on my server I get the usual "unmarshalling return" error. Problem is that my Object I'm trying to return actually implements the Remote interface:
public interface Bank extends Remote {
     public Account create_account (String name) throws BankException, RemoteException;
};the Implementation looks like this:
public class BankImpl implements Bank {
     public Account create_account (String name) throws BankException {
          Account k = new AccountImpl(name);
          return k;
}Again the interface and Implementation:
public interface Account extends Remote {
    public Account(String name);
public class AccountImpl implements Account, Remote  {
     private String name = null;
     AccountImpl(String name){
          this.name = name;
};I'm quite stuck here, is there something I'm missing??? I thought that function whose return type is some implementation of the Remote interface will automatically get passed by reference with an automatically generated stub.

It seems to me that having to actually extend the UnicastRemoteObject is quite a limitation.You don't have to. I gave you that as the simplest solution. If you don't extend UnicastRemoteObject, you have to export the object yourself with UnicastRemoteObject.exportObject(). Use the overload where you specify a port number, even if it's only zero (= any).
And somehow I'm unable to cast the generated Proxies to my Interfaces.
Actually I can only let my extend the "Remote" interface in my interfaces and them implement my Account interface and extend "UnicastRemoteObject" in the implementations and still it won't work.What happens? You'll have to show us the code ... btw is there something missing back there?
Still think I'm missing something...For sure. RMI works.
