Thanks for the suggestions Kevin! I'd like to stay clear of listeners if I can so I can keep it localized to the handful of use cases where I actually need it :/
I'm not sure if this is the best solution or not, but I seem to be running out of practical solutions that will keep metadata isolated. I figured that in this case I'm already using a native query. So, why not just capture the connection from the entity manager and create the native statement that will allow access to the metadata. The only problem is the entityManager.unwrap(java.sql.Connection.class) seems to be unpredictable. Sometimes I receive "java.lang.IllegalStateException: No transactional EntityManager available" and entityManager.getEntityManagerFactory().createEntityManager().unwrap(java.sq l.Connection.class) likes to call "synchronizeMappings" in JDBCBrokerFactory#newBrokerImpl(String user, String pass) even though the OpenJPA documentation (version 2.2.1) indicates that the lack of "openjpa.jdbc.SynchronizeMappings" will prevent such a call. Maybe I'm missing something here? -----Original Message----- From: Kevin Sutter [mailto:kwsut...@gmail.com] Sent: Thursday, January 24, 2013 9:34 AM To: users@openjpa.apache.org Subject: Re: OpenJPA + Native Query = Meta Data Not that I am aware of... Of course, OpenJPA has access to and utilizes the metadata while processing the result set, but I don't see a means of providing that metadata back to the application. Since OpenJPA is open-source, we always welcome new feature submissions... :-) One alternative that might work for you is to tie into OpenJPA's JDBC Listeners [1]. If you tied into the post execute statement listener, you could get access to the jdbc-related artifacts and do your own parsing of the information. Maybe not quite as easy as the eclipselink feature, but would that provide the metadata you are looking for?
