[jboss-user] [JBoss Seam] - Second level cache (ehcache) working?

[shakenbrain]

Has anyone been able to get ehcache working in a Seam application?  I've enabled ehcache in my persistence unit:

         <property name="hibernate.cache.use_second_level_cache" value="true"/>
  |          <property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider"/>

and enabled caching for one of my entities:

@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
  | public class Organization extends PersistentObject {
  | ...
  | }

I created a basic ehcache.xml file as follows:

<ehcache>
  | 
  |     <diskStore path="java.io.tmpdir"/>
  | 
  |     <defaultCache
  |         maxElementsInMemory="10000"
  |         eternal="false"
  |         timeToIdleSeconds="120"
  |         timeToLiveSeconds="120"
  |         overflowToDisk="true"
  |         diskPersistent="false"
  |         diskExpiryThreadIntervalSeconds="120"
  |         memoryStoreEvictionPolicy="LRU"
  |         />
  | 
  | </ehcache>

I put ehcache.xml into a jar file called ehcache.jar in server/default/lib so ehcache is able to find it.  Where is this file really supposed to go?  Does it really have to live there because that's where ehcache-1.2.3.jar is?

After loading an entity in my Seam application I update it in underlying database using an external application.  I would expect the entity to remain unchanged when viewing in it my Seam application because the object should be cached, but it's obviously being reloaded from the database.

Any ideas?
