Re: [eclipselink-dev] WG: @QueryHint(name = QueryHints.QUERY_RESULTS_CACHE, value = HintValues.TRUE)

Hi Adrian,

Exactly what version are you running on? Have you done anything special to the configuration? The nightly tests, and my local run both pass that test.

Seems that the very feature I was investigating just stopped working in the very same moment … -Adrian _____________________________________________

*Betreff:* @QueryHint(name = QueryHints.QUERY_RESULTS_CACHE, value = HintValues.TRUE) Hi, I am experiencing trouble with this query hint @NamedQuery(name = "getAllDepartmentsCached", query = "select d from Department d", hints = { @QueryHint(name = QueryHints.QUERY_RESULTS_CACHE, value = HintValues.TRUE) })
public class Entity Department {
The first time, I am executing the named query, I get the expected result. But if I execute it again, the result is empty: *public* *void* testCachedQueryWithoutParameters() *throws* SQLException {
        EntityManager em = getEnvironment().getEntityManager();
        *try* {
            Query query = em.createNamedQuery("getAllDepartmentsCached");
            List<Department> result = query.getResultList();
            /assertEquals/(result.size(), 2);
result = query.getResultList();
            /assertEquals/(result.size(), 2); <<<<< size is 0 now!
        } *finally* {
Are there any preconditions I’d have to fulfill in order to uses the QUERY_RESULTS_CACHE hint? I have switched the default caching off: <property name="eclipselink.cache.shared.default" value="false"/> Any ideas? -Adrian *Adrian Görler
