Hi there,
I'm trying to migrate our "old" J2EE1.4 / EJB2.1 applications persistence to openJPA. Currently I got stuck when trying to configure OpenJPA persistence, when creating the EntityManagerFactory and the EntityManager instance, I get the following error: <4|true|0.9.6-incubating> org.apache.openjpa.persistence.InvalidStateException: Could not perform automatic lookup of EJB container's javax.transaction.Transact ionManager implementation. Please ensure that you are running the application fr om within an EJB 1.1 compliant EJB container, and then set the org.apache.openjp a.ManagedRuntime property to the appropriate value to obtain the TransactionMana ger. at org.apache.openjpa.ee.AutomaticManagedRuntime.getTransactionManager(A utomaticManagedRuntime.java:180) at org.apache.openjpa.kernel.AbstractBrokerFactory.syncWithManagedTransa ction(AbstractBrokerFactory.java:598) at org.apache.openjpa.kernel.BrokerImpl.initialize(BrokerImpl.java:292) at org.apache.openjpa.kernel.AbstractBrokerFactory.newBroker(AbstractBro kerFactory.java:165) at org.apache.openjpa.kernel.DelegatingBrokerFactory.newBroker(Delegatin gBrokerFactory.java:139) at org.apache.openjpa.persistence.EntityManagerFactoryImpl.createEntityM anager(EntityManagerFactoryImpl.java:187) Currently I'm running the application within the JOnAS 4.8.3 J2EE Server. How can I configure open JPA to use the provided managed Transactions of JOnAS? (this works also with Hibernate 2.x so I assume it should somehow be possible with openJPA?) any help appreciated! regards, HANS =========================== virtually hanzz... <http://hanzz.zapto.org> http://hanzz.zapto.org (personal) <http://www.cse.dmu.ac.uk/~hansp> http://www.cse.dmu.ac.uk/~hansp (research)
