[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5303) @Cachable has no effect

[Paul Bakker (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37418#action_37418 ] 

Paul Bakker commented on HHH-5303:
----------------------------------

I already did some debugging. I don't see anything wrong so far. I get to the setCache method with "cacheAnn" = null. So it appears the problem is not in the annotation processing. Does the following setting override the annotation?

{code}
<property name="hibernate.ejb.classcache.demo.entities.Employee"
                      value="read-write"/>
{code}

If that's the case, the problem is that without it caching doesn't work.

> The JPA 2.0 @Cachable annotation has no effect at all. Just putting @Cachable on a class is not enough to enable caching. You must also configure a concurrency strategy with either @Cache or a hibernate.ejb.classcache setting in persistence.xml. 
> If those settings are in place, @Cacheble still has no effect. Entities are cached, but @Cachable(false) doesn't change this behavior. 
> I included a Maven example project that tests this behavior. The project has two profiles to switch between Hibernate and EclipseLink:
> mvn -P hibernate clean test
> mvn -P eclipselink clean test
