Hi, I've set up a jboss server with a few EJBs and JBoss cache running on the same server. My persistence.xml is deployed with the following options
| <property name="hibernate.cache.use_second_level_cache">true</property>
| <property name="hibernate.cache.use_query_cache">true</property>
| <property name="hibernate.cache.provider_class">org.hibernate.cache.TreeCacheProvider</property>
|
and one of my entity beans has the following annotations
| @Entity
| @Table(name = "album", uniqueConstraints = {...}) @Cache(usage=CacheConcurrencyStrategy.TRANSACTIONAL)
|
Everything starts up correctly, no error messages etc.
I now use some SLSBs to get Entity beans etc. from an external client, which is a standalone java app, and I am expecting the the server side to use the cache as configured, but it's not working as I'd expect.
First my client complains that
Exception in thread "main" org.hibernate.HibernateException: Could not instantiate cache implementation
| at org.hibernate.cache.CacheFactory.createCache(CacheFactory.java:64)
| at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:214)
| at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1218)
| at fm.last.catalogue.test.TestClient.<init>(TestClient.java:62)
| at fm.last.catalogue.test.TestClient.main(TestClient.java:251)
| Caused by: org.hibernate.cache.NoCachingEnabledException: Second-level cache is not enabled for usage [hibernate.cache.use_second_level_cache | hibernate.cache.use_query_cache]
| at org.hibernate.cache.NoCacheProvider.buildCache(NoCacheProvider.java:21)
| at org.hibernate.cache.CacheFactory.createCache(CacheFactory.java:61)
| ... 4 more
The only references i've found about this indicate that you need to include those three lines above to the hibernate.cfg.xml file in the client side. So i do so. And now everything works.
BUT!
I don't see any sign that caching is actually happening on the server. I get these messages in my client log (saying there are no other members in the cluster etc.) and the server remains absolutely silent. Which makes me think i've just created a cache in the client, which is not what i want.
What am i configuring wrong?
(below is a section of the trace from the client, and the mbean for EJB3EntityTreeCache as deployed in the server)
Many thanks.
