Appendix D: Hibernate Test Application Source Code
This appendix provides the contents of the following two Hibernate Test Application source code files:
•HibernateSessionFactory.java
•hibernate.jsp
The following are the contents of the HibernateSessionFactory.java file:
package com.hp.osms.hibernate.utility; import org.hibernate.HibernateException; import org.hibernate.Session;
import org.hibernate.cfg.Configuration;
public class HibernateSessionFactory {
private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";
private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>(); private static Configuration configuration = new Configuration();
private static org.hibernate.SessionFactory sessionFactory; private static String configFile = CONFIG_FILE_LOCATION;
private HibernateSessionFactory() {
}
public static Session getSession() throws HibernateException { Session session = (Session) threadLocal.get();
if (session == null !session.isOpen()) { if (sessionFactory == null) {
rebuildSessionFactory();
}
session = (sessionFactory != null) ? sessionFactory.openSession():null; threadLocal.set(session);
}
return session;
}
public static void rebuildSessionFactory() { try { configuration.configure(configFile); sessionFactory = configuration.buildSessionFactory(); } catch (Exception e) {
System.err.println("Can not create SessionFactory!!"); e.printStackTrace();
}
}
public static void closeSession() throws HibernateException { Session session = (Session) threadLocal.get(); threadLocal.set(null);
if (session != null) session.close();
}
public static org.hibernate.SessionFactory getSessionFactory() { return sessionFactory;
}
public static void setConfigFile(String configFile) { HibernateSessionFactory.configFile = configFile; sessionFactory = null;
}
}
The following are the contents of the hibernate.jsp file:
<%@ page language="java" import="java.util.*,
org.hibernate.HibernateException, org.hibernate.Query,org.hibernate.Transaction, com.hp.osms.hibernate.utility.HibernateSessionFactory, com.hp.osms.hibernate.Users"
