Okay, I will try to explain my problem more detailed. I have several entity classes that have different semantics but same syntax. They are called Type because - they typify other objects. Therefore they consist of a short key string and a description. Such a type could be currency with the ISO 3 letter key and the currency's name or the ISO language code and the language's name. For accessing from outside they all have the same pattern: - Get all elements of a type. - Get one element by its key. - Add an element. - Change an element. - Remove an element. (Hm, sounds like scaffold...) Now I have a dozen of this types. Creating one service function for each type and each access mode is not very object oriented. Also I would get a service with about 60 almost identical functions. So with generics it shrinks to one function for each access mode. <T extends Type> T add(T t); <T extends Type> T save(T t); <T extends Type> T remove(T t); <T extends Type> Collection<T> findAll(Class<T> clazz); <T extends Type> T findByKey(Class<T> clazz, String key); But the model language does not allow such generics. Which makes it hard to write such a service. I hope, this could clearify my intentions.
