Hi! Sorry for the cross-posting, but it's really urgent!

I'm currently migrating our JBoss Cluster from 4.2.3 to 5.1.0. We already have almost everything working, just a small piece is missing: Pojo Cache.
We make heavy use of this feature, so all/any help on this is much appreciated!

My configuration in JBossAS 4.2.3 is:

cat jboss423/server/all/deploy/pojocache-service.xml:

In my work to migrate this config to something equal in jboss 5.1.0, I got something like this.

cat jboss510/server/all/deploy/pojocache-service.xml:
Code:

The problem is i can't define an eviction policy and/or maxNodes attribute. I know i'm doing something wrong (obviously), but i can't undestand what.

Examples on how to configure this properly are welcome!
