Hi,

I have a configuration xml file, from which my SessionFactory is configured.

I need something like:

Code:

but to map a directory not a concrete file.

With java code it is possible, but I want to know, if this is possible in xml configuration file, because I don't want to spread configuration all over the code, but to have it in one place. I need this, because my cfg.xml files are dinamicly created?

Thanks in advance!

vb.net: you can try this in the nhibernatehelper class or when you configure your session factory:

Code:

Imports System
Imports System.Web
Imports NHibernate
Imports NHibernate.Cfg

Namespace NHWebSite
    Public NotInheritable Class NHibernateHelper

        Public Const CurrentSessionKey As String = "nhibernate.current_session"
        Public Shared ReadOnly sessionFactory As ISessionFactory

        Shared Sub New()
            Dim x As New NHibernate.Cfg.Configuration
            x.AddDirectory(yourdir)
            sessionFactory = x.Configure.BuildSessionFactory()
        End Sub

...

Tanks for your reply :)

I know, that it is possible to do this in code, but I want to have all configuration in the configuration file. I don't want to have parts of configuration in different places. Most of the configurations can be done in code and in xml file. But it seems, that this one can not be done in xml file!

Yes, it's true, I understand your problem.
The way I do that is putting this row in the config file:

Code:

"NHWebSite" is the name of my project and the namespace of my entities and classes.

Code:

...
Namespace NHWebSite
    Public NotInheritable Class NHibernateHelper 
...

In this way, when I create new entities and xml files in this namespace, I don't need to touch the config file.
I don't know if <mapping directory="" /> is allowed, Have you tried this?

Another option is to provide a configuration item to your application that contains a path and your application can get the contents of the directory and add each found mapping file to the NHibernate configuration in code.

Cheers,

Symon.

I am sorry, but I saw now, that I posted a topic in the wrong forum. This is a question for Hibernate, not NHibernate.

Sorry again!
