I have a doubt about the result of a query.
I have a table like User(id,name,surname,phone) and i want to query this table in my EJB in this way:
List res = em.createQuery("select u.id, u.name from User u where u.phone='555321').getResultList();
What kind of object there are inside res?
I have tryed to cast res in a List but it doesn't work.
How can i do to access the data in res list??
Thanks to all.
I have solve the problem!!
res is a List<Object>
