Some code. Problem in UPDATE query.
TypedQuery<List<Transport>> query = (TypedQuery<List<Transport>>) em.createQuery("SELECT t FROM Person p JOIN p.transports t WHERE p.personalCode = :code"); query.setParameter("code", personalCode); List<List<Transport>> list = query.getResultList(); List<Transport> temp = new Vector<Transport>(); temp.add((Transport) attributeValue); list.add(temp); TypedQuery<Person> query2 = (TypedQuery<Person>) em.createQuery("UPDATE Person p SET p.transports = :list WHERE p.personalCode = :code", Person.class); query2.setParameter("list", list); query2.setParameter("code", personalCode); query2.executeUpdate();
