"Note that if you make MyService a @Singleton, then you should inject
Provider<EntityManager> instead."
When should MyService be a singleton? If I am using the DAO without state,
i.e. injecting it into my Servlets for processing through a Provider,
should it be a one and done created object? I am creating a new one each
time, but have noticed that on message boards people say to make the DAO
Services singletons, is that right?
