Hi all,

I'm doing a program that saves customer details to the database and I'm using NHibernate. I'm very new in it and I'm getting help from the net. I have a problem compiling the mapping file, I get the following error:
"Could not compile the mapping document: Customer.hbm.xml"

I don't have an idea of what I did wrong. Please, if you know what I missed or did wrong, I'd really appreciate your help/advice. Thanks.

hibernate.cfg.xml
<?xml version="1.0" encoding="utf-8" ?>
<configuration>

Customer.hbm.xml

<?xml version="1.0" encoding="utf-8"?>
<!--<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0"> -->

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="NHibernate" namespace="NHibernate_Demo" >

<class name="NHibernate_Demo.Customer, NHibernate_Demo"
table="Customers" lazy="false">
<id name="CustomerID" type="String" length="5">

</id>
<property name="CompanyName" column="CompanyName" type="String" length="40"/>
<property name="ContactName" column="ContactName" type="String" length="30"/>
<property name="ContactTitle" column="ContactTitle" type="String" length="30"/>
<property name="Phone" column="Phone" type="String" length="24"/>

</class>
</hibernate-mapping>

Here is my class:

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using NHibernate.Cfg;

namespace NHibernate_Demo
{

class Program
{
static void Main(string[] args)
{

// Loads the NHibernate Types to prepare for Serialization
Configuration cfg = new Configuration();
cfg.Configure();

//cfg.AddAssembly(typeof(NHibernate_Demo.Customer).Assembly);
//cfg.AddClass(typeof(Customer));
cfg.AddFile("Customer.hbm.xml");

//Opens a session to NHiberbate to allow us to work with objects
ISessionFactory sessionsF = cfg.BuildSessionFactory();

//let ISessiionFactory open connection
ISession sessionS = sessionsF.OpenSession();

ITransaction transaction = sessionS.BeginTransaction();
{
Customer customer = (Customer)
sessionS.Load(typeof(Customer), "ALFKI");

// Show the Contact Name of the Customer
//MessageBox.Show(customer.ContactName);

sessionS.Close();
}


}

}

}


I get an error at this line:

cfg.AddFile("Customer.hbm.xml");

Thanks.
