I’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 🙂

Could 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]]

Sent the zip file without libraries. I really appreciate you looking into this! Thank you 🙂

[[email protected]]

Note: 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…

I 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

Thank 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?

[email protected] ,

Please add this on start rebuildSessionFactory (copy this method from my previous post)

if (sessionFactory != null)
         return; 

Regards,

I 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…

Please 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 you

This is complete class with static initializer.

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();
      }
    }

That seems to have fixed my issue! I really appreciate the time and effort you put into helping me on this.

Thank you very much!!! 🙂
