Code between sessionFactory.openSession() and session.close():
String inputString1_Code_Qual = "REPAIR CATA";
String inputString2_Elem_Nbr = "TIG12790";
List result = null;
Query q = sess.getNamedQuery(Tidcvval.QUERY_READ_TIDCVVAL_DATES_BLANK);
		 	q.setString("InputString_CodeQualVal",inputString1_Code_Qual);
		 	q.setString("InputString_ElementNbr",inputString2_Elem_Nbr);
result = q.list();
		
Name and version of the database you are using:Oracle 9i
I have the appropriate QUERY_READ_TIDCVVAL_DATES_BLANK definition in Tidcvval.java the value object. 
However when i run my test the result size is zero whereas when i  execute the sql that is being logged using p6spy it shows that there are 6 records in the DB which ofcourse is true. 
So can anybody tell if am doing something wrong , because the sql that is being logged as result of getNamedQuery works , but the getNamedQuery as such does not work.
Thanks and Regards
