У меня есть сеансный компонент без сохранения состояния (slsb), который зависит от двух других bean-компонентов, которые действуют как DAO. Они оба используют JPA, поэтому у каждого боба есть EntityManager. Они указывают на разные единицы персистентности (которые, в свою очередь, представляют собой разные пулы соединений с одной и той же базой данных - я не хочу жертвовать этой гибкостью).
В простом коде это выглядит так (имена в моем приложении, конечно, настоящие имена):
@Stateless
public class MyBean {
@EJB
private Dao1 dao1;
@EJB
private Dao2 dao2;
}
@Stateless
public class Dao1 {
@PersistenceContext(unitName = "unit1")
private EntityManager em1;
}
@Stateless
public class Dao2 {
@PersistenceContext(unitName = "unit2")
private EntityManager em2;
}
Когда я получаю доступ к методам Dao1 и Dao2 в MyBean, я всегда получаю следующую ошибку:
SEVERE: Unable to complete container-managed transaction.; nested exception is: javax.transaction.SystemException: org.omg.CORBA.INTERNAL: JTS5031: Exception [org.omg.CORBA.INTERNAL: vmcid: 0x0 minor code: 0 completed: Maybe] on Resource [rollback] operation. vmcid: 0x0 minor code: 0 completed: No

После включения многословия регистраторов CORBA , Контейнер EJB , JTA и JTS в FINEST следующие строки появляются непосредственно перед исключением:

FINE: An XAException occurred in prepare
Ничего другого (кроме тысяч FINE: TM: enlistComponentResources и FINE: TM: delistResource, но они выглядят нормально).
Оба пула подключений настроены как XADataSource. Мой текущий обходной путь заключается в том, что один из двух DAO использует эту аннотацию:
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
Не думаю, что это хорошее решение, но я не знаю, как это исправить иначе. Можно ли лучше избавиться от этой ошибки?
