Code where the exception happens is on the 'return line where the cast is:

public FlightReservationAccessorRemote getFlightReservationAccessorRemote() throws NamingException
  | {
  |         return (FlightReservationAccessorRemote)fetchRemoteObject( "flightReservationAccessorRemote", "FlightReservationAccessorBean" );
  | }

Lookup is done here:

private Object fetchRemoteObject(String key, String clsName ) throws NamingException
  |     {
  |         Object ret = null;
  |         if( cache.containsKey( key ))
  |         {
  |             ret = cache.get( key );
  |             log.info( "Got it from CACHE..." );
  |         }
  |         else
  |         {
  |             if( ctx != null )
  |             {
  |             	log.info(clsName );
  |                 ret = ctx.lookup( "reservation/" + clsName + "/remote");
  |                 if( ret != null )
  |                 {
  |                     cache.put( key, ret );
  |                 }
  |             }
  |         }
  |         return ret;
  |     }
