I have some questions about transaction
1 If the db(informix 7) does not support transaction, the session bean's TransactionAttribute must to be not_support?If not, it is required by default. i got a RollbackException.
2 when I test the same method with DefautDS(hypersonic) of JBoss, if TransactionAttribute is not_support, i got exception below, Is it normal?
Exception in thread "main" javax.persistence.TransactionRequiredException: EntityManager must be access within a transaction
| at org.jboss.ejb3.entity.ManagedEntityManagerFactory.verifyInTx(ManagedEntityManagerFactory.java:150)
| at org.jboss.ejb3.entity.TransactionScopedEntityManager.persist(TransactionScopedEntityManager.java:181)
3 how can i use these 2 DataSources in one method? I created 2 EntityManager, but there is always an exception because of transaction.
thanks in advance
