[jboss-user] [JBossCache] - Re: EJB3 + JBossCache, accessing from external client

[bstansberry@jboss.com]

On the server side, use

<property name="hibernate.cache.provider_class">org.jboss.ejb3.entity.TreeCacheProviderHook</property>

That provider knows how to talk to the jboss.cache:service=EJB3EntityTreeCache service.

It's not clear to me from your post whether you want second-level caching on the client side. 

1) If you do, sound's like it's at least semi working. You just need to be sure that the JBoss Cache configuration on the client side matches the one on the server side.

2) If you don't, include this in your hibernate.cfg.xml:

<property name="hibernate.cache.use_second_level_cache">false</property>
  | <property name="hibernate.cache.use_query_cache">false</property>

Hibernate defaults to 'true' on 'use_second_level_cache' so if you mark any of your entities as cacheable it will throw the exception you posted when you don't configure a provider. Explicitly setting the config to false should get around the problem.
