I'm new to NHibernate and am trying to build a simple app that uses NHibernate to store presist information to a SQL database. I'm using Visual Web Developer 2005 Express Edition. When I run the program I get the following error:

NHibernate.HibernateException: The hibernate.connection.driver_class must be specified in the NHibernate configuration section.
at NHibernate.Connection.ConnectionProvider.ConfigureDriver(IDictionary settings)
at NHibernate.Connection.UserSuppliedConnectionProvider.Configure(IDictionary settings)
at NHibernate.Connection.ConnectionProviderFactory.NewConnectionProvider(IDictionary settings)
at NHibernate.Cfg.SettingsFactory.BuildSettings(IDictionary properties)
at NHibernate.Cfg.Configuration.BuildSettings()
at NHibernate.Cfg.Configuration.BuildSessionFactory()

my hibernate.cfg.xml file is located in the Bin dictory and looks like:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section
name="nhibernate"
type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
/>
</configSections>

<nhibernate>
<add
key="hibernate.connection.provider"
value="NHibernate.Connection.DriverConnectionProvider"
/>
<add
key="hibernate.dialect"
value="NHibernate.Dialect.MsSql2000Dialect"
/>
<add
key="nhibernate.connection.driver_class"
value="NHibernate.Driver.SqlClientDriver"
/>
<add
key="hibernate.connection.connection_string"
value="[...]"
/>
</nhibernate>
</configuration>

Any and all ideas are welcome. Thanks in advance.

You have nhibernate.connection.driver_class in config. Remove the leading "n"

thanks for the reply, but I'm still having problems. I added the following lines to my code-behind:

cfg.AddFile(Server.MapPath("~/Person.hbm.xml"));
cfg.Configure(Server.MapPath("~/Bin/hibernate.cfg.xml"));

that took care of the driver_class problem but now I'm getting:

NHibernate.MappingException: The dialect was not set. Set the property hibernate.dialect. ---> NHibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect.
at NHibernate.Dialect.Dialect.GetDialect()

at NHibernate.Cfg.Configuration.AddXmlFile(String xmlFile)
--- End of inner exception stack trace ---
at NHibernate.Cfg.Configuration.AddXmlFile(String xmlFile)
at NHibernate.Cfg.Configuration.AddFile(String xmlFile)

the only thing I've changed in my config file is hibernate.connection.driver_class (used to have nhibernate.....). Everything else in the config file is the same as above.

My Professor and I spent about an hour messing with the code until it worked. In the end we just started over, so problem solved. Thanks for the help.
