When I save a new entry to the database using hibernates Session.saveOrUpdate(Object) it gets saved to the local database but does not get replicated to my other server.

Updates to the database are working fine, so If I load an object using hibernate, change it and then resave it using Session.saveOrUpdate(Object). These changes get replicated to all databases.

My treecache configuration is:

<server>
 <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/>

Is there something I am missing from my configuration?

My hibernate setup is:

<property name="hibernateProperties">
 <props>
 <prop key="hibernate.dialect">org.hibernate.dialect.FirebirdDialect</prop>
 <prop key="hibernate.show_sql">true</prop>
 <prop key="hibernate.cache.provider_class">org.hibernate.cache.TreeCacheProvider</prop>
 <prop key="hibernate.treecache.mbean.object_name">VicopCache</prop>
 <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</prop>
 <prop key="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</prop>
 <prop key="hibernate.cache.use_query_cache">true</prop>
 </props>
 </property>

thanks for your time,
