Given existing entity classes, one can create either an EJB facade for these classes, or a JPA controller. However, the generated code is quite inconsistent between the two:

- names of the finder methods that return all entities: findCustomerEntities() (controller) vs. findAll() (facade)
- names and parameter type of the finder methods that return a single entity: findCustomer(Integer id) vs. find(Object id)
- finder parameters when finding a subset of results: (int maxresults, int firstresult) vs. (int[] range)
- there seems to be a difference in the TRANSACTIONAL vs. EXTENDED persistence context type and the closing of EntityManager (but I guess that's understandable)
