Hi All I too would much rather see @NamedQuery(ies) defined in a seperate class like I do other more complicated queries. I also see this as a good way of keeping things modular or decoupled from the model.
Using a seperate java class which then registers those queries at run time would be a good way of doing things. The registration not need be in the persistence.xml file as long as it can be added to the persistence unit later.
