I agree that JPA can be clunky. I have found the CriteriaBuilder way of building queries to be manageable (if a bit verbose). So far, I’ve used JQL queries (defined in @NamedQuery annotations) for the queries that have a well-defined structure, and CriteriaBuilder for the more complex cases (such as filtering by a user-defined set of parameters). My use cases have been relatively simple, though.
