You'll have to use instanceof to determine the type returned by the
Unmarshaller if you don't know it ahead of time...
Object obj = unmarshaller.unmarshal(reader);
if (obj instanceof res.xmlerror.Transactflex) {
}
or if all your objects use a base class you can cast to the base class:
TransactflexBase transactflex = (TransactflexBase)
unmarshaller.unmarshal(reader);
