Brad Koehn commented on OPENJPA-1277:
-------------------------------------
I would love to have this feature. I have an application that needs to support
generic, user-created, persistent queries (think reports). I'd love to give the
user a UI that stores a JPQL query in the database. But when I run that query,
I need to apply the (dynamic, also user-specified) security rules to the query.
For this I'd love to have the user query in a Criteria format so that I can
enhance it with whatever security filters are required. But since there's no
good way to serialize a criteria query, translating JPQL to Criteria would be a
great step.

> Develop a mechanics to generate a Criteria Query from a JPQL string.
> A mechanics to convert an existing JPQL string into a Criteria Query will
> ease adoption of the new API.
> The conversion mechanics should operate both a design-time (to emit Java
> source code) as well as runtime (to instantiate of Criteria Query
> instances).
