Hibernate version:
Hibernate 2.1
Mapping documents:

I am trying to use jboss treecache using the treecache.xml file that was shipped with hibernate. After adding the
<cache usage="transactional"> tag in the relecant hbm.xml file, and
<property name="hibernate.cache.provider_class">net.sf.hibernate.cache.TreeCacheProvider</property>
in the hibernate.cfg.xml file, I couldn't get it to work with the original treecache.xml file.

But when i removed the
<attribute name="ClusterConfig">
..................
</attribute>

I was able to verify that the particualr class was being cached.

When I tried adding back the following tag (straight out of the original file):

- <attribute name="ClusterConfig">
- <config>
<UDP mcast_addr="228.1.2.3" mcast_port="45566" ip_ttl="64" ip_mcast="true" mcast_send_buf_size="150000" mcast_recv_buf_size="80000" ucast_send_buf_size="150000" ucast_recv_buf_size="80000" loopback="false" />
<PING timeout="2000" num_initial_members="3" up_thread="false" down_thread="false" />
<MERGE2 min_interval="10000" max_interval="20000" />
<FD shun="true" up_thread="true" down_thread="true" />
<VERIFY_SUSPECT timeout="1500" up_thread="false" down_thread="false" />
<pbcast.NAKACK gc_lag="50" retransmit_timeout="600,1200,2400,4800" up_thread="false" down_thread="false" />
<pbcast.STABLE desired_avg_gossip="20000" up_thread="false" down_thread="false" />
<UNICAST timeout="600,1200,2400" window_size="100" min_threshold="10" down_thread="false" />
<FRAG frag_size="8192" down_thread="false" up_thread="false" />
<pbcast.GMS join_timeout="5000" join_retry_timeout="2000" shun="true" print_local_addr="true" />
<pbcast.STATE_TRANSFER up_thread="false" down_thread="false" />
</config>
</attribute>


I get this exception

Again, I could see it work without this tag. I need to get this thing working for replicated/clustered cache. What am I missing? Thank You.

I'm using the same config without problems. What version of jboss are you using?

Short Answer: JBoss 4.0.0

Long Answer: I am not running this test in the JBoss container. I just included all JBoss jar files (that was shipped along with Hibernate) in the class path. Would that be a problem? Hibernate In Action books says all JBoss server specific configuration would be simply ignored in a non-Jboss environment.

Also, since the cache usage is set to transactional, I thought may be this would work only in an managed environment. So I tried running this under Weblogic 8.1 (again with Jboss jars in the classpath), no luck there either. Container or no container, I get the same error.

<ClusterConfig> attribute is a jgroups configuration which is used by treecache as transport layer, no matter in jboss or standalone. I've just cut-n-paste your quoted config to my jboss-cache.xml config and no errors appeared. Visually I see no difference with my own config.
I suggest you take jboss-cache.jar and jgroups.jar whether from the latest treecache distribution or jboss distribution (I've just tried in jboss-3.2.6 release and it's ok) because they could by outdated in hibernate distrib (in particulary jgroups.jar)

That fixed it. Thank You.
