[jboss-user] [JBossCache] - JBossCache - RpcDispatcher:257 - exception marshalling objec

[sebas23]

Good evening,
I am trying to configure JBossCache for Hibernate in Weblogic 9.2. I am using hibernate-3.2.5, jbosscache-1.4.1sp4 and jgroups-2.4.1-sp4. I can see the two nodes from the cluster establish their communication when everything gets initialized, i.e. stuff like:
22:58:07,257 DEBUG GMS:435 - [local_addr=10.222.64.80:57141] view is [10.222.64.91:57141|1] [10.222.64.91:57141, 10.222.64.80:
57141]
(I basically use the treecache.xml provided on the wiki)

Now, when hibernate loads objects and tries to replicate them accross, I get a load of exceptions like the one below. I can't figure out what setting I am missing/what could be the problem at this point. All the jar files are in in the APP-INF/lib folder in my application ear file so it should be a problem to load. I would definitely appreciate any help!

Thanks in advance,
Seb
