I have application written in Java that is using EJB3 + Toplink. I m using Glassfish as my app. server.
Sometimes the data that has been cached is old and I need to clear my cache manually. I know that we can set time to clear it, but I would like to make a button that will manually clear it for me. Is is possible to do?
Apparently you can refresh cache with you query your database using this code:
Query query = em.createQuery(sql.toString()).setHint("toplink.refresh", "true");
This works for me.
I think it is better to use:
em.createNamedQuery("findAll").setHint(QueryHints.CACHE_RETRIEVE_MODE, CacheRetrieveMode.BYPASS).getResultList();
it works for me and I think it is more standard way.
