[email protected]MemberI’m using MyEclipse 5.1GA and created a project with Hibernate 3.1, JSF, and Web capabilities. I configured hibernate for one table to use a Tomcat 5.5 JNDI data source and have a simple .jsp page that accesses that table using a backing bean. The first time I launch the page Hibernate errors when loading the configuration (see error stack below). I submit the page again and then the configuration loads and everything is well. It is like the process is not waiting for the Hibernate configuration to load…. I appreciate any help you can offer 🙂

Haris PecoMemberCould you send example of project (if it is possible) which throw this log on [email protected] with subject ATTN: snpe (you haven’t to send libraries).You have some threading problem and I can’t reproduce it ?
Thanks,
[email protected]MemberSent the zip file without libraries. I really appreciate you looking into this! Thank you 🙂
[email protected]MemberNote: I have a few more tables condifugred now in the zip provided but still gets the provided error because the Userinfo table is the first thing used at login… Once I get Hibernate to load the other tables and Userinfo work fine… Weird…
Haris PecoMemberI can reproduce your case.
Please, try change HibernateSessionfactory#rebuildSessionFactory to :public synchronized static void rebuildSessionFactory() { if (sessionFactory != null) return; try { configuration.configure(configFile); sessionFactory = configuration.buildSessionFactory(); } catch (Exception e) { System.err .println("%%%% Error Creating SessionFactory %%%%"); e.printStackTrace(); } }
Sorry for the inconvenience caused .
I will try update hibernate templates
[email protected]MemberThank you for your quick responses!!! The .jsp page still comes back with an error and the “cannot read Userinfo.xbm.xml” is on the console but I can see the console continue on and load the Hibernate configuration. It seems the create session is not waiting until it is done? Is there a way to make it wait until it is loaded?
Haris PecoMemberPlease add this on start rebuildSessionFactory (copy this method from my previous post)
if (sessionFactory != null) return;
Regards,
[email protected]MemberI did put this in?
/**
* Rebuild hibernate session factory
*
*/
public static void rebuildSessionFactory() {
if (sessionFactory != null)
return;
try {
configuration.configure(configFile);
sessionFactory = configuration.buildSessionFactory();
} catch (Exception e) {
System.err
.println(“%%%% Error Creating SessionFactory %%%%”);
e.printStackTrace();
}
}I still get ther error…
%%%% Error Creating SessionFactory %%%%

Haris PecoMemberPlease try add static initializer.Sorry for inconvvenience caused, but I don’t like static initializer, because I sometime want use this class for configration only (without building session factory).
Please, send us if it helps.
Thank youThis is complete class with static initializer.
import org.hibernate.HibernateException; import org.hibernate.Session; import org.hibernate.cfg.Configuration; /** * Configures and provides access to Hibernate sessions, tied to the * current thread of execution. Follows the Thread Local Session * pattern, see {@link http://hibernate.org/42.html }. */ public class HibernateSessionFactory { /** * Location of hibernate.cfg.xml file. * Location should be on the classpath as Hibernate uses * #resourceAsStream style lookup for its configuration file. * The default classpath location of the hibernate config file is * in the default package. Use #setConfigFile() to update * the location of the configuration file for the current session. */ private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml"; private static final ThreadLocal threadLocal = new ThreadLocal(); private static Configuration configuration = new Configuration(); private static org.hibernate.SessionFactory sessionFactory; private static String configFile = CONFIG_FILE_LOCATION; static { try { configuration.configure(configFile); sessionFactory = configuration.buildSessionFactory(); } catch (Exception e) { System.err .println("%%%% Error Creating SessionFactory %%%%"); e.printStackTrace(); } } private HibernateSessionFactory() { } /** * Returns the ThreadLocal Session instance. Lazy initialize * the <code>SessionFactory</code> if needed. * * @return Session * @throws HibernateException */ 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; } /** * Rebuild hibernate session factory * */ public synchronized static void rebuildSessionFactory() { try { configuration.configure(configFile); sessionFactory = configuration.buildSessionFactory(); } catch (Exception e) { System.err .println("%%%% Error Creating SessionFactory %%%%"); e.printStackTrace(); } } /** * Close the single hibernate session instance. * * @throws HibernateException */ public static void closeSession() throws HibernateException { Session session = (Session) threadLocal.get(); threadLocal.set(null); if (session != null) { session.close(); } } /** * return session factory * */ public static org.hibernate.SessionFactory getSessionFactory() { return sessionFactory; } /** * return session factory * * session factory will be rebuilded in the next call */ public static void setConfigFile(String configFile) { HibernateSessionFactory.configFile = configFile; sessionFactory = null; } /** * return hibernate configuration * */ public static Configuration getConfiguration() { return configuration; }
and this is change from standard MyEclipse session factory :
static { try { configuration.configure(configFile); sessionFactory = configuration.buildSessionFactory(); } catch (Exception e) { System.err .println("%%%% Error Creating SessionFactory %%%%"); e.printStackTrace(); } }
[email protected]MemberThat seems to have fixed my issue! I really appreciate the time and effort you put into helping me on this.
Thank you very much!!! 🙂
Haris PecoMemberYou are welcome.Thank you for your patience and sorry for the inconvenience caused.
I will try update templates in shortlyBest regards,
