[jboss-user] [JBossCache] - JBoss cache newbie question about using regions with POJO ca

[yair.zaslavsky]

Hi all,
I started to use JBossCache several days ago, and succeeded to run the examples.

I want to use POJO cache, and to set a region for FQN "/people/friends"

Here is the configuration file I used:



    


    <!-- ==================================================================== -->
    <!-- Defines TreeCache configuration                                      -->
    <!-- ==================================================================== -->

    

        jboss:service=Naming
        jboss:service=TransactionManager


        <!-- Configure the TransactionManager -->
        org.jboss.cache.BatchModeTransactionManagerLookup


        <!--
            Node locking level : SERIALIZABLE
                                 REPEATABLE_READ (default)

                                 READ_UNCOMMITTED
                                 NONE
        -->
        REPEATABLE_READ

        <!--

                             INVALIDATION_ASYNC

        -->

I am using it as standalone application (not inside JBOSS AS or any other cotainer).
I placed different objects in cache under
/people/friends/A
/people/friends/B
/people/friends/C
/people/friends/D
/people/friends/E
/people/friends/F

I implemented my own TreeCacheListener and set it in the cache,so I can see if there is an eviction (I simply printed out messages for all handlers defined in the class implementing TreeCacheListener).
I did not see any eviction of nodes (although I set in the configuration that the max nodes for the regions in 2).
Can you please tell me what I'm doing wrong?
(I'm JBossCache 1.4.1.SP6)
