DetachedCriteria Query

[shinerella]

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: org.jboss.ejb3.entity.InjectedHibernateSession

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

Remark:

In debugging time into the first step getSearchCriteria()

what happens is the following

My "contains" variable has a string value: "DEPP" , so it seems to go ok adding the restriction, and it also returns me that "searchCriteria" .
