Hi, i try to get the home interface with AirportHome airportHome = AirportHome)PortableRemoteObject.narrow(home, AirportHome.class); in a XSP Cocoon page. I always get a ClassCastException with the value null. In another application (not a servlet) it works fine. What can be th reason for this error ?
