TransactionRequiredException

[tonyukuk]

I just wanted to delete a row from the database

String delete="delete from Price where id=:priceId";
Query q=this.getEntityManager().createQuery(delete);
q.setParameter("priceId",priceId);
q.executeUpdate();

I made sure that I am not violating foreign key constraint and I used  usertransaction class and methods but id didn't work, too.

try {
utx.begin();
System.out.println("done");
q.executeUpdate();
utx.commit();
} catch (Exception e) {
System.out.println("error");
     }

You can see the error that I get below;

Exception during request processing:

Why aren't you using the @Transactional annotations on your method?

[tonyukuk]

it didn't work either

[thejavafreak]

Have you set up your transaction component in components.xml ?

Hi,

I had the same problem few minutes ago. But I've manage to sort it out. Insteand of using getEntityManager() method, I declared @In EntityManager entityManager as a member of the EntityHome, and is working now, I don't understand yet why, because I have also other methods in the same class where I using getEntityManager, and I don't have any problem.

Same problem here, in spite of using @Transactional (why?)

Resolved by calling joinTransaction(), see EntityHome.update() for an example.
