The solutions posted here not worked for me. But i've made it work with: @Cache @NamedQueries({@NamedQuery( name = "State. FindAll", query = "SELECT s FROM State s", hints = { @QueryQUERY_RESULTS_CACHE, value = TRUE) } )}).

Exactly, QueryCACHE_USAGE is for the use of second level cache. If you want query cache the hint you have QueryQUERY_RESULTS_CACHE – Pau Oct 29 '10 at 13:10.

Just a guess here, but you might try query. CacheQueryResults(); after you create it but before you getResultList. -- MarkusQ.

The JPA Query object does not support the cacheQueryResults() method. If I instead create a ReadObjectQuery I don't know how (or if I can) ask it for a list? – rustyshelf Feb 25 '09 at 5:59 If you don't want to use the eclipselink especific query, you have to use hints.

It can be done through annotations, as Andre explained or through query. SetQUERY_RESULTS_CACHE, TRUE) – Pau Oct 29 '10 at 13:12.

I got EclipseLink 1.0.1 cache to work by adding just the query hint: Query query = em. CreateNamedQuery("Person. Find"); query.

SetParameter("NAME", name); query. Setcache-usage", "CheckCacheThenDatabase"); return (Person)query.getSingleResult(); I didn't change the entity at all, and haven't yet tried to configure cache using annotations.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
