Hi Scott,
Thanks a lot for your help. I'm going to try what you suggest. I'm also
going to add the timestamp to avoid problems such as if users connect at
sometime using different browsers ("newt" + username + timestamp). I will
let you know later if these changes fix the problem.
We also have another application that only uses hibernate core that I also
upgraded from 3.6.1 to 4.1.8 and the duplicate entity factory problem
doesn't seems to happen. Is it normal?
When using only hibernate core 4.x my oracle sessions are never closed even
after I close SessionFactory and I don't understand why. This problem
doesn't happen in any of the 3.6.x versions. I already wrote to the mailing
list but I still didn't get any feedback. The email subject is "Problem
closing oracle session with hibernate 4.1.8". Do you have any idea of what
can be the problem?
Best regards,
Teresa

Teresa,
I made a code change in Hibernate 4.x that impacts
serialization/deserialization of EntityManagerFactories. My code change
helps Hibernate to work correctly in clustered environments (HHH-6897) but
it looks like my change also broke your application. In a clustered
environment, each entity manager factory will have a unique name.
In your application, could you try setting
"hibernate.ejb.entitymanager_**factory_name"
to a unique name? Perhaps you could try setting it to:
"newt" + username
