    Madhav Sapre Newbie

      Hi,
      I'm trying to configure JBoss POJOCache to be used with JBoss AS. I have configured POJOCache MBean in the jboss-service.xml as follows


      jboss:service=Naming
      jboss:service=TransactionManager
      REPEATABLE_READ
      REPL_ASYNC
      DefaultCluster
      5000
      10000
      15000
      org.jboss.cache.eviction.LRUPolicy


      20

      10000
      0





      I do not want to use CacheLoader as I want to have control over what goes into cache through our DAO layer. I get following exception when I
      start JBoss

      I'm new to JBoss Cache. Can someone advise if I can use JBoss Cache with JBoss AS without specifying CacheLoader? If so, how do I configure
      POJOCache MBean in jboss-service.xml?

      Thanks in advance.
