Problem returning a transfer object
I'm trying to develop a Session EJB which will be used for invocations over IIOP. I have set up a test client and have managed to call a method that returns a String object. However, when i try to call a method that returns a transfer object i.e. an obejct that is an implementation of the Transfer object pattern, i get the following error:
java.rmi.RemoteException: CORBA UNKNOWN 0 No; nested exception is:

Here are the two different methods that I use.
// This one works fine
public String getFolderName(long id)
throws RemoteException, FinderException;
// This one results in an exception
public Folder findFolder(long eid)
throws RemoteException, FinderException;
The client is started as follows:
