    TransactionRequiredException

    Germiyan Ogul Newbie
      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;
