I switched to nHibernate release 2.0 beta 2. I received
Could not find the dialect in the configuration and then changed the config section in App.config. When I received the error again, I made the changes based on the release notes and the info at http://www.manning-sandbox.com/thread.jspa?messageID=72781. But it's still not working. Any ideas? Thanks --

<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler,NHibernate" requirePermission="false"/>
</configSections>

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.0">
<session-factory>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string">Data Source=localhost;initial catalog=MyDb;Integrated Security=SSPI</property>
</session-factory>
</hibernate-configuration>

This works -- based on info from a website that I forgot the URL for ---

<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
</configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory>
<property name="dialect">
NHibernate.Dialect.MsSql2005Dialect
</property>
<property name="connection.provider">
NHibernate.Connection.DriverConnectionProvider
</property>
<property name="connection.driver_class">
NHibernate.Driver.SqlClientDriver
</property>
<property name="connection.connection_string">
Server=localhost;
Database=MyDb;
Integrated Security=True;
</property>
</session-factory>
</hibernate-configuration>

the difference being changing:

urn:nhibernate-configuration-2.0

TO

urn:nhibernate-configuration-2.2

hello

What's urn in mapping file for?

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">

Also I changed to 2.2 and still getting the same message:

InnerException = {"Could not find the dialect in the configuration"}

My xml file seems simple (and flawless)

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">

<class name="Util.Person, Util" table="Person">
<id name="Id" column="Id" type="Int64" unsaved-value="0">
<generator class="native" />
</id>
<property name="FirstName" column="FirstName" type="String(50)"/>
<property name="MiddleName" column="MiddleName" type="String(50)"/>
<property name="LastName" column="LastName" type="String(50)"/>
<property name="Login" column="Login" type="String(50)"/>
<property name="PrimaryEmail" column="PrimaryEmail" type="String(255)"/>
<property name="PasswordHash" column="PasswordHash" type="Int32"/>

</class>
</hibernate-mapping>

And I'm using this version: "NHibernate-2.0.1.GA-bin.zip"

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">

That's the namespace declaration. Can you post your configuration ? There are some breaking changes with 2.0.

thanks it turns out to be fact I didn't call "Configure" before adding assembly!


Configuration cfg_AuditTrail = new Configuration();
cfg_AuditTrail.Configure("../../AuditTrail.hibernate.cfg.xml");
ISessionFactory oNHFactory_AuditTrail = cfg_AuditTrail.BuildSessionFactory();
oContext.NhibernateConfigFactories.Add(Util.NHibernateDBUtil.AUDITTRAIL, oNHFactory_AuditTrail);
cfg_AuditTrail.AddAssembly(typeof(Util.Security.AuditTrailLog).Assembly); // This should be the one and only assembly to add.

See above, I should have called "Configure()" before calling "AddAssembly".

Thanks though - but wish to know more about the urn tag. The significance of it...?

Afaik in that case it's primarily used as some kind of versioning for the schema definition. There've been changes in the schema with nhib 1.2.
