[jboss-user] [JBossCache] - EvictionPolicyConfig

[kevinstembridge]

Hi all,
I'm having trouble getting an eviction policy to work properly for objects that are not in a top-level tree node. 
 
I'm using JBossCache as the 2nd-level cache for Hibernate. So, for example, if I am caching an object called my.package.MyClass, it ends up in a cache region called /my/package/MyClass. To set up an eviction policy for this region I am using the following config:


  |       <attribute name="EvictionPolicyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
  |       <!-- Specific eviction policy configurations. This is LRU -->
  |       <attribute name="EvictionPolicyConfig">
  |          <config>
  |             <attribute name="wakeUpIntervalSeconds">5</attribute>
  |             <!-- Cache wide default -->
  |             <region name="/_default_">
  |                <attribute name="maxNodes">5000</attribute>
  |                <attribute name="timeToLiveSeconds">30</attribute>
  |             </region>
  |             <region name="/my/package/MyClass" >
  |                <attribute name="maxNodes">10000</attribute>
  |                <attribute name="timeToLiveSeconds">10</attribute>
  |                <attribute name="maxAgeSeconds">10</attribute>
  |             </region>
  |          </config>
  |       </attribute>
  | 

But the result I'm seeing is that the eviction policy for the specific region is not applied. 

However, things work fine if I tell Hibernate to store objects in a top-level region (i.e. not nested) and provide an eviction policy for that region. 

BTW, using JBossCache 1.4 with Hibernate 3.2.0 in JBoss 4.0.5.

Any help is much appreciated.

Kevin
