EJB QL returning null, it should not

[infonote]

This EJB QL query is returning null, when it should not. Can someone point me in the right direction.
What is wrong with my EJB QL query?

And i call it from the struts action.

Thanks in advance.

public java.util.List findTrip(String placefrom, String placeto) throws Exception{
 List q = null;
 try {

 q = (List) em.createQuery("SELECT OBJECT(b) FROM Bookingline b WHERE " +
 "b.bkLPlaceFrom = :sessionName AND b.bkLPlaceTo " +
 "= :sessionName2").setParameter("sessionName",placefrom)
 .setParameter("sessionName2",placeto).getResultList();

 } catch (NoResultException en) {

 en.printStackTrace(); // just to be sure, maintain this enabled until finish debugging.
 return q = null;
 } catch(Exception ex) {
 ex.printStackTrace(); // just for debugging. You will find errors like missing space between WHERE and clauses...
 throw ex; // just rethrow exception...
 }

 return q;
 }


 public java.util.List tripSearch(String placefrom, java.lang.String placeto) throws Exception {
 List q = null;

 q = findTrip(placefrom,placeto);

 System.err.println(q==null?"tripSearchReturned NULL":"tripSearch returned "+q.size());



 return q;
 }
