Im trying to use a Detached Criteria to make my queries. But I ran into a
problem. Here I describe the situation
I have this class with the parameters to make the search, where I also define a
Detached Criteria . that later on I 'll use on my session bean
@Name("searchParameters")
| public DetachedCriteria getSearchCriteria()
| {
|
| searchCriteria = DetachedCriteria.forClass(CAROPrince.class);
|
| if (contains != null)
| {
| searchCriteria.add(Restrictions.ilike("code", contains,
MatchMode.ANYWHERE));
| }
|
| return searchCriteria;
| }
|
then I have a bean PrinceSearchAction
|
| public class PrinceSearchAction implements Serializable, PrinceSearch
| {
| @PersistenceContext(unitName = "princes")
| private Session session;
|
| @PostConstruct
| public void setSession()
| {
| HibernateUtil.setSession(session);
| }
|
| @In(required = false, create = true)
| private CAROPrince prince;
|
| @In(required = false, create = true)
| PrinceSearchParameters searchParameters;
|
| @Out(required = false)
| private List<CAROPrince> returnprinces;
|
|
| public String findPrinces()
| {
| try
| {
| DetachedCriteria searchCriteria =
searchParameters.getSearchCriteria();
| Criteria crit =
searchCriteria.getExecutableCriteria(session);
| crit.setMaxResults(100);
| returnprinces = crit.list();
| }
|
| if (returnprinces.size()>0)
| {
| return "found";
| }
| else
| {
| return "notfound";
| }
|
| catch ( Exception e )
| {/**
| * TODO:Implement error handeling when looking for princes in
the future :)
| */
| e.printStackTrace();
| return "error";
| }
| }
|
|
WELL, there is always problems when we search for a prince, but my problem is
exacly in this line
-> Criteria crit = searchCriteria.getExecutableCriteria(session);
And I get the following exception :
INFO [STDOUT] java.lang.ClassCastException:

What Im doing wrong? Is that a correct way to use the detachedCriteria?
