This is because Hibernate comes with a 'Provider' class for each major cache it supports; a wrapper that abstracts Hibernate code from cache product specifics.

Thanks for the tip, but now i get another error:
10:24:38,851 ERROR [Hibernate] Starting failed jboss.har:service=Hibernate org.hibernate.cache.CacheException: org.jboss.cache.ConfigureException: could not find resource treecache.xml
But if i rename treecache-service.xml to treecache.xml and put it in my classpath it works. No errors and it seems the members in the cluster finds each other. Not shure this is the correct approach.
Now i have to find out if replication really works between hibbernate instances.

Yes, Hibernate does require that you call your config file treecache.xml. You should also be able to specify JNDI properties so that it picks up the shared TreeCache instance bound to JNDI by the app server though...
