CDI @TransactionAttribute for bean

Question

I am experimenting with `CDI` on a test application. I have a `DAO` which injects a container managed `JTA` persistence context like this: ``` public class TestDAO implements Serializable { @PersistenceContext private EntityManager entityManager; public void insertEntity(Test test) { entityManager.persist(test); } } ``` Now I have a CDI controller bean like this: ``` @Named @SessionScoped public class TestController implements Serializable { @Inject private TestDAO testDAO; public void finishGame() { testDAO.insertEntity(new Test(1, 2, 3)); } } ``` If I run this, I receive an error in the `DAO` when trying to insert the entity, because there is no active transaction available. So far so good. I can solve this by making the controller bean a stateful `EJB` which will wrap the `finishGame()` in a transaction. But let assume I don't want an `EJB`. As a test I annotated the `finishGame()` with the `@TransactionAttribute` annotation and it worked(the controller bean is NOT an `EJB`). So my…

Accepted Answer

You need do define a transaction interceptor. Basically define a @Transactional annotation and intercept all methods annotated with it. In the interceptor just begin, commit or rollback the transaction. It gets more complicated when transaction propagation comes into the picture. So check if Seam doesn't have anything ready-to-use http://seamframework.org/Seam3/PersistenceModule
