I am using weblogic 7.0.5 in clustered environment. When i am executing the transaction I am getting the following error. Do in need to do any setting on weblogic side. It works fine in non-clustered environment.

Session session = HibernateUtil.currentSession();
Transaction tx = session.beginTransaction();
for(int i=0;i<al.size();i++){

Please, provide me if you found any solution for this.

Why are you trying to register the SessionFactory with the JNDI service?

The session factory is not a clusterable object. I ran into the same problem and the SessionFactory was only available to the first machine that was brought up in the cluster. We solved the problem by adding this property to our Hibernate config:



This will keep weblogic from trying to replicate the SessionFactory in the cluster. Keep in mind that each node in the cluster has it's own SessionFactory instance independent of one another. Generally, this is not a big deal. But if your using a second-level cache, you'll need to make sure your cache is clusterable.
