How to get data?

I use reflection to run a function in a Dao.
However, after : List<Hotel> size = (List<Hotel>)session.createQuery("from Hotel t").list(); , I can see the sql is printed out in MyEclipse console, but the program is stop here.

The code snippet is as follows:

public class AppServiceDao {

public AppServiceDao(){}
private SessionFactory getSessionFactory() {
return (SessionFactory)SpringContextUtils.getBean("sessio nFactory");
}

@SuppressWarnings({ "unchecked", "deprecation" })
private String HotelBySeq(Long city, Integer startNo, Integer endNo) throws
HibernateException,SQLException{
StringBuilder sb = new StringBuilder("<?xml version=\"1.0\" encoding=\"UTF-8\"?>")

Session session = this.getSessionFactory().openSession();//.getCurrentSession();
session.beginTransaction().begin();
String hql="from Hotel t ";
List<Hotel> size = (List<Hotel>)session.createQuery(hql).list();
session.flush();
session.clear();
session.close();
.................................................. .....
I try .getCurrentSession(); but it has same problem. How to get data?
