I'm having difficulty debugging internals of glassfish.
Here's when I want to persist the object of type Queue:
Queue queue = (Queue)session.getAttribute("cart");
EntityManager em = WebAppManager.getInstance().getEntityManagerFactory().createEntityManager();
em.getTransaction().begin();
//account = em.merge(account);
queue.setAccount(account);
em.persist(queue);
em.getTransaction().commit();
em.close();
I get an exception from (signin.jsp):
java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 0

etc...
I tried many things, I just don't have an idea, which array is empty...
or if I am going in wrong direction... any help would be welcome.
