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 Scott On 01/08/2013 08:03 AM, Teresa Batista Neto wrote: > Hello, > > I just copy/past the exception call stack from when the "registry > contains more than one" error is thrown.
