Iterate List of entities

[vikramchhetryy]

Hi all,
I am getting class cast exception when I try to execute this code in this line
roles = (Roles) it.next();

public void loadRolesList() {
 List<Roles> list = (List<Roles>) em
 .createQuery(
 "select r.iroleId, r.strDescription from Roles r order by r.iroleId")
 .getResultList();
 log.info("Query executed = " + list.size());
 Roles roles;
 ListIterator<?> it = list.listIterator();
 while(it.hasNext()){
 roles = (Roles) it.next();
 log.info("Id = " + roles.getIroleId());
 rolesList.add(new SelectItem(roles.getIroleId(), roles
 .getStrDescription()));
 }
 }

I am not sure if it is the right way of doing it but I want to iterate the list in java only.

Any help would be appreciated.

Thanks,
Vikram

Problem fixed.
I modified my code:

 public void loadRolesList() {
 Collection<Roles> list = em.createQuery(
 "select object(r) from Roles r order by r.iroleId")
 .getResultList();

 for (Roles roles : list) {
 rolesList.add(new SelectItem(roles.getIroleId(), roles
 .getStrDescription()));
 }
 }

Thanks,
Vikram
