It seems that Hibernate is not aware of Atomikos Transaction Manager. in previous version of Hibernate(3.5) there were parameters you had to provide that were called:
hibernate.transaction.manager_lookup_class = com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup hibernate.transaction.factory_class = com.atomikos.icatch.jta.hibernate3.AtomikosJTATransactionFactory OR org.hibernate.ejb.transaction.JoinableCMTTransactionFactory I know Hibernate 4 is "able" to get the current transaction Manager and do not need these parameters anymore but never tested... -- View this message in context: http://camel.465427.n5.nabble.com/Need-help-with-Camel-JPA-Atomikos-tp5713578p5713656.html Sent from the Camel - Users mailing list archive at Nabble.com.
