Object is not getting persisted using JPA/JTA/JBOSS/CDI

Question

Please help me to understand why object is not getting persisted with following code. It throws javax.persistence.TransactionRequiredException: JBAS011469: Transacti

Answer 1

I'm not too familiar with EJBs, but I believe the problem is that without the @Stateless annotation, the bean is not a EJB, so transactions are not automatically managed. If you need statefulness, use the @Stateful annotation to make a stateful EJB. If you do not want to use EJBs, you have to manually manage your transactions using the EntityManager like so.

tx = em.getTransaction();
tx.begin();

// do some work
...

tx.commit();

Answer 2

When you declare the bean as @Stateless then the methods in that bean are by default transactional. Transactional methods commit the persistence state when fully executed.

When you don't have your class annotated with @Stateless methods are not transactional by default and hence you get the mentioned exception.
