Session factory does not implement ISessionFactoryImplementor.

[Dargor]

Hello every one,

I have been using nhibernate for a few months and learned a whole lot
through this time (like how to set it up to work in medium trust
environments). However today while uploading my application to my
shared hosting environment I got the following error:

Session factory does not implement ISessionFactoryImplementor.

I am currently using NHibernate in a ASP.NET application with the
following property for Session Context :

<property name="current_session_context_class">web</property>

As in most examples in the web I have a NHibernateHelper class with
the following code:

public static class NHibernateHelper
{
private static ISessionFactory _sessionFactory = null;

// Lock synchronization object
private static object _syncLock = new object();

//private static void NHibernate()
//{
//}

/// <summary>
/// Opens a NHibernate Session using a configuration
file.
/// </summary>
/// <param name="configFile">Path to the configuration
file used for
this session</param>
/// <returns>ISession object</returns>
/// <exception cref="ZiblerDataLayerUtilitiesException"/
>
/// <remarks>If no session has been created a new
session will be
open.
/// Otherwise the existing session will be returned.</
remarks>
public static ISession OpenSession(string configFile)
{
// Support multithreaded applications through
// 'Double checked locking' pattern which (once
// the instance exists) avoids locking each
// time the method is invoked
if (_sessionFactory == null)
{
lock (_syncLock)
{
if (_sessionFactory == null)
{
try
{
Configuration
cfg = new Configuration();
_sessionFactory
= cfg.Configure(@configFile).BuildSessionFactory
();

//if
(SessionFactory == null)
// throw new
Exception("MARIO NULL");

}
catch
(HibernateException e)
{
throw new
ZiblerDataLayerUtilitiesOpenSessionException
(Resources.OpenSessionExceptionMessage, e);
}
catch (Exception e)
{
throw new
ZiblerDataLayerUtilitiesUnknownException
(Resources.UnknownExceptionMessage, e);
}

}
}
}

return _sessionFactory.OpenSession();
}

/// <summary>
/// Returns the current session
/// </summary>
/// <returns>Current session</returns>
public static ISession GetCurrentSession()
{
return _sessionFactory.GetCurrentSession();
}

/// <summary>
/// Returns the current Session Factory
/// </summary>
public static ISessionFactory SessionFactory
{
get { return _sessionFactory; }
}

}


So basically the architecture of my application is a conversation by
request, in which I bind the session to the request at the beginning
and unbind it at the end. It is when I unbind that this problem
appears. When I unbind I have to pass the SessionFactoy (retrieved
from the NHibernateHelper class) to the Nhibernate
CurrentSessionContext.Unbind method. What I notice is that when I get
the Session Factory from the NhibernateHelper class, it is always
null. I know it is not a mapping issue since it works in my
development environment.

Note that the class shown above is a static class that all my http
requests use when opening a session. However I have come to realize
that because it is static, it gets loaded into the aspnet process in
the server, and it won't be unloaded until this process is rebooted.

I have a feeling that the reason for this problem is because of this,
however I don't have the ability to reboot the aspnet process since
this is a shared hosting, and I do need to update my app constantly
(specially during development). Any ideas????? Hope you can help.

Thanks in advance

Mario
