why Hibernate criteria return empty list if I have data in my table?

I didn't understand why I am getting empty list from `criteria`, and I have data in my table. code where I'm getting List: ``` hibernateSession_destination = HibernateUtilReports.INSTANCE.getSession(); Criteria criteria = hibernateSession_destination.createCriteria(nr_rec_backup_rule.class); List list = criteria.list(); System.out.println("List length ======= " + list.size()); // prints size = 0 ``` My HibernateUtilReports.java : ``` public enum HibernateUtilReports { INSTANCE; public static SessionFactory sessionFactory = null; private synchronized SessionFactory getSessionFactory(){ if(sessionFactory == null){ Configuration config = new Configuration(); config.addAnnotatedClass(contaque_recording_log.class); config.addAnnotatedClass(contaque_servers.class); config.configure("reportshibernate.cfg.xml"); // is here any error??? Properties configProperties = config.getProperties(); ServiceRegistryBuilder serviceRegisteryBuilder = new ServiceRegistryBuilder(); ServiceRegistry serviceRegistry = serviceRegisteryBuilder.applySettings(configProperties).buildServiceRegistry(); sessionFactory = config.buildSessionFactory(serviceRegistry); } return sessionFactory; } public Session getSession(){ return getSessionFactory().openSession(); } } ``` My reportshibernate.cfg.xml: ``` <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="connection.url">jdbc:oracle:thin:@8080/xe</property> <property name="hibernate.connection.username">user</property> <property name="hibernate.connection.password">1234</property> <property name="c3p0.minPoolSize">2</property> <property name="c3p0.maxPoolSize">100</property> <property name="c3p0.timeout">1000</property> <property name="hibernate.cache.use_second_level_cache">false</property> <property name="show_sql">true</property> <property name="hibernate.connection.zeroDateTimeBehavior">convertToNull</property> </session-factory> ``` Where am I going wrong??? Edited: Note: Since "show_sql" is set to 'true' in my xml, but I am not getting any SQL query on my console.
