Hi,

I am new to NHibernate. I have downloaded the NHibernate and tried with my vs.net 2003 very much the same example given in the quick tutorial.

I am receiving the below error at
// Tell NHibernate that this object should be saved
session.Save(newUser);

Error is:
Unhandled Exception: NHibernate.MappingException: Unknown entity class: nhibernate.User

Please help.

My hbm.xml is given below

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="nhibernate.User,nhibernate" table="users">
<id name="Id" column="LogonId" type="String" length="20">
<generator class="assigned" />
</id>
<property name="UserName" column="Name" type="String" length="40"/>
<property name="Password" type="String" length="20"/>
<property name="EmailAddress" type="String" length="40"/>
<property name="LastLogon" type="DateTime"/>
</class>
</hibernate-mapping>

User.cs is the same example file


I am calling the object like the following
private void Form1_Load(object sender, System.EventArgs e)
{
// try
// {
Configuration cfg = new Configuration();
//cfg.AddAssembly("MyNHibernate.Examples");
cfg.AddAssembly("nhibernate");
ISessionFactory factory = cfg.BuildSessionFactory();
ISession session = factory.OpenSession();
ITransaction transaction = session.BeginTransaction();

User newUser = new User();
newUser.Id = "joe_cool";
newUser.UserName = "Joseph Cool";
newUser.Password = "abc123";
newUser.EmailAddress = "joe@cool.com";
newUser.LastLogon = DateTime.Now;

// Tell NHibernate that this object should be saved
session.Save(newUser);

// commit all of the changes to the DB and close the ISession
transaction.Commit();
session.Close();

Make sure that you pass the assembly that contains your mapping files and classes to the cfg.AddAssembly and make sure that the Build Option for the mapping files are set as Embedded Resource in the Visual Stidio.
