I am constructing my new application using the following structure.
App (Storing the solution files only)
--- App.Web (web.config including the NHibernate configuration)
--- App.BLL
--- App.BO (POCO objects)
--- App.DAL (NHibernateHttpModule and BaseDataAccess from Beansoftware)

The sessionFactory is configured inside the NHibernateHttpModule which located in the DAL assembly. It seems not able to read the configuration file in the web.config. I am able to create another configuration inside the DAL project but I don't want to scatter my configuration.

Moreover, is there any good sample or recommendation with n-tier architecture with NHibernate available?

Code reference:
http://www.beansoftware.com/ASP.NET-Tut ... g4Net.aspx

Error Message:
The hibernate.connection.driver_class must be specified in the NHibernate configuration section.

Hi,

The problem looks like NH doesn't can look the web.config with the configuration.

Did you read this article ?
http://www.codeproject.com/KB/architect ... tices.aspx

By the way, we are waiting for NHibernate.Burrow, that is the brand new project of NHibernate.Contrib. NHB will provide the capabilities for managment of NHibernate Session.

Best regards

I've figured out the problem now. You are right. Hibernate can't read the web.config file. I just know that I need to add the reference of System.Web into my class library. The hibernate can read the config automatically now. Thanks.

For the best practice project, I have already got it before. However, I am not strong in OOP. It takes me more time to understand it.
