Hi, I´m new with NHIbernate....if anyone know the answer...

I open a webApplication an configured the files like this :

web.config

<!-- Add this element -->
<configSections>
<section
name="hibernate-configuration"
type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"
/>
</configSections>

<!-- Add this element -->
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.0">
<session-factory>
<property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="connection.connection_string">Server=(local);initial catalog=valmir;Integrated Security=SSPI</property>
</session-factory>
</hibernate-configuration>

cliente.cs
public class Cliente
{
public Cliente()
{
}

private int idCliente;
public int getIdCliente()
{
return idCliente;
}
public void setICliente(int value)
{
idCliente = value;
}

private string descricaoCliente;
public string getDescricaoCliente()
{
return descricaoCliente;
}
public void setDescricaoCliente(string value)
{
descricaoCliente = value;
}
}

cliente.hbm.xml

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

<class name="Cliente" table="Cliente">

<id name="idCliente" column="idCliente" type="Int32" length="4" unsaved-value="0">
</id>

<property name="descricaoCliente" column= "descricaoCliente" type="String" length="50"/>

</class>

</hibernate-mapping>

AND in the webform

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

using NHibernate;
using NHibernate.Cfg;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//ISessionFactory s = new NHibernate.Cfg.Configuration().Configure().BuildSessionFactory();

ISession session = NHibernateHelper.GetCurrentSession();

ITransaction tx = session.BeginTransaction();

Cliente c = new Cliente();
c.setICliente(9999);
c.setDescricaoCliente("9999");

session.Save(c);

tx.Commit();
}
}


public sealed class NHibernateHelper
{
private const string CurrentSessionKey = "nhibernate.current_session";
private static readonly ISessionFactory sessionFactory;

static NHibernateHelper()
{
sessionFactory = new NHibernate.Cfg.Configuration().Configure().BuildSessionFactory();
}

public static ISession GetCurrentSession()
{
HttpContext context = HttpContext.Current;
ISession currentSession = context.Items[CurrentSessionKey] as ISession;

if (currentSession == null)
{
currentSession = sessionFactory.OpenSession();
context.Items[CurrentSessionKey] = currentSession;
}

return currentSession;
}

public static void CloseSession()
{
HttpContext context = HttpContext.Current;
ISession currentSession = context.Items[CurrentSessionKey] as ISession;

if (currentSession == null)
{
// No current session
return;
}

currentSession.Close();
context.Items.Remove(CurrentSessionKey);
}

public static void CloseSessionFactory()
{
if (sessionFactory != null)
{
sessionFactory.Close();
}
}
}

AND When I run GET THE MESSAGE Unknown entity class !!!



Can someone help me !!! Thanks.

no need to "shout" !!!

What version of .NET are you using?
- if you are using 1.1 check if the mapping files are "embedded Resources".
- if you are using 2.0 you can't embed them so: either build a separate class library project with your business objects, and then you can mark them as embeded resources, either use the new "Web Application Projects" template for Visual Studio 2005 - you have to download the template from Microsoft - this I think will allow you to embed resources - it implements the "old" ASP.NET 1.x web project model.

HTH,
radu

Thank you very much Radu !!!

Now works.......
