Hi, I am integrating JBoss Cache 3.0.2 into our app which hitherto used Spring's org.springframework.orm.hibernate3.HibernateTransactionManager (which delegates to Our hitherto stack is as follows: Spring 2.5.6 C3p0 Cnx pool Hibernate 3.3.1 Tomcat 6 We are running in a cluster, and will only (initially at least) need async invalidation. Given the above, do I really need a full-blown JTA impl (like Atomikos or JOTM) or can I get away with creating a delegate impl of JTA that would: - implement javax.transaction.TransactionManager, Transaction, UserTransaction - have MyTransaction delegate to org.hibernate.Transaction wherever possible - do nothing on Transaction.enlistResource/delistResource - do implement registerSynchronization - implement own org.hibernate.transaction.factory_class and manager_lookup_class - my javax.transaction.Transaction impl would delegate back to Hibernate's JDBCTransaction I am wondering whether this is possible because it seems that JBossCache 3 only uses Synchronization and never Transaction.enlistResource. thanks -nikita View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4207833#...
