> URL: https://issues.apache.org/jira/browse/CAMEL-10265
> Project: Camel
> Issue Type: New Feature
> Components: camel-jpa
> Reporter: Darius Cooper
> Assignee: Tomohisa Igarashi
> Fix For: Future
>
>
> Consider a use-case where a message has some content (say a list of IDs) that
> we want to transform into a list of objects retrieved from the database. One
> could do this by using the camel-sql component as a producer. However, I
> don't think there's good way to do this using the camel-jpa component.
> As a producer, camel-jpa does not support named-queries. We have some places
> where we use JPA over some tables, but in use-cases like this, we switch to
> camel-sql for that step, or code a processer. Workable, but a slight
> impedance mis-match.
> It would be nice to add support for named-query (and related options) to the
> producer in camel-jpa.
