Hallo !

Got some Problems with upgrading our Caching.We want to use Hibernate 3.5.2 and JBossCache 3.2.5.

We got two Tomcats on different machines. Everyone has cache and they syncronize via JGroups/udp.

It is my task to upgrade now.

At Start i see that hibernate(withc3p0) starts and cache seems to start too because I see this line on console and its similar
to the former version:

GMS: address is (cluster=JBossCache-cluster)

In the following trace a CommandAwareRpcDispatcher had an error

6040 [main] INFO org.hibernate.impl.SessionFactoryObjectFactory - Not binding factory to JNDI, no JNDI name configured
6040 [main] INFO org.hibernate.cache.UpdateTimestampsCache - starting update timestamps cache at region: org.hibernate.cache.UpdateTimestampsCache
6041 [main] INFO org.hibernate.cache.StandardQueryCache - starting query cache at region: org.hibernate.cache.StandardQueryCache
2010-05-28 09:49:26,225 (main                      CommandAwareRpcDispatcher.java:387 ) ERROR java.lang.NullPointerException

but Hibernate can get  a List of entities from the Database.

In my next lines, I instanciate a new entity start saving via Hibernate.

But now it crashes with this:

2010-05-28 09:49:26,397 (main                      CommandAwareRpcDispatcher.java:387 ) ERROR java.lang.NullPointerException
6510 [main] ERROR org.hibernate.event.def.AbstractFlushingEventListener - Could not synchronize database state with session
org.hibernate.cache.CacheException: org.hibernate.cache.CacheException: java.lang.RuntimeException: Failure to marshal argument(s)

Can anyone give me a hint, where to look to solve the problem?

thx Dirk
