In my application, when user logs in to the system the system reads some setting from DB and stores them on user's session. The system is performing this action by a JPA query using EclipseLink (JPA 2.0).
When I change some settings in DB, and sign in again, the query returns the previous results. It seems that EclipseLink is caching the results.
I have used this to correct this behavior but it does not work:
query.setHint(QueryHints.cache_usage,cacheUsage.no_cache);
