AFAICT, to get replication of an SFSB with an extended PersistenceContext to work, your persistence.xml needs to declare the "hibernate.session_factory_name" property, e.g.: | <?xml version="1.0" encoding="UTF-8"?> | <persistence> | <persistence-unit name="tempdb"> | <jta-data-source>java:/DefaultDS</jta-data-source> | <properties> | <property name="hibernate.session_factory_name" value="tempdb"/> | <property name="hibernate.hbm2ddl.auto" value="create-drop"/> | </properties> | </persistence-unit> | </persistence> | Without this, when the EntityManager is deserialized on the remote node, you get this: | Caused by: java.io.InvalidObjectException: could not resolve session factory during session deserialization [uuid=8a8b8eac10c785e70110c788056b0001, name=null] | at org.hibernate.impl.SessionFactoryImpl.deserialize(SessionFactoryImpl.java:1056) | at org.hibernate.impl.SessionImpl.readObject(SessionImpl.java:1892) | ... 78 more | To avoid the IOException, Hibernate needs a name for the factory, which is provided via the property. But having to specify that property seems funky. Could the value of the persistence-unit element's name attribute be passed to the SessionFactory as its name?
