public class CheckMe {
@SuppressWarnings("unchecked")
public static void getData(){
EntityManagerFactory factory =
Persistence.createEntityManagerFactory("hellojpa");
EntityManager em2 = factory.createEntityManager();
Query q = em2.createQuery("SELECT
f.gazCountyCode,f.gazTownCode,f.gazTownName FROM GazTown f").setMaxResults(5);
System.out.println("Size::"+q.getResultList().size());
List<GazTown> results = q.getResultList(); ---->
ClassCastException here
System.out.println(results.get(0).toString()+"<<< Sizeoo
>>>::::::"+q.getResultList().size());
for (GazTown m : results) {
System.out.println("Success:::"+m.getGazTownName());
}
em2.close();
factory.close();
}
Note: I am getting the result and the size is being shown as 5. But when I cast
the resultset, then I get the exception.
