i'm having a mapping exception. it seems as though it cannot find a persister for a class.
plz, any help would be greatly appreciated
i have the following config for hibernate

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory name="moe">
<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">Data Source=MISU-SA\DBSERV;Database=MOE;User ID=;Password=r;</property>
<property name="connection.isolation">ReadCommitted</property>
<property name='proxyfactory.factory_class'>NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
<property name="show_sql">true</property>
<!-- HBM Mapping Files -->
<mapping assembly="MOE.Core" />
</session-factory>
</hibernate-configuration>

here is the class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using MOE.Core.VO;

namespace MOE.Core.Domain
{
public class News : DomainObject<int>
{
private int id;
private string title;
private string body;
private DateTime date;
private string tags;
private string teaser;

public News()
{

}

public News(int pId, string pTitle, string pBody, DateTime pDate, string pTags, string pTeaser)
{
this.id = pId;
this.title = pTitle;
this.body = pBody;
this.date = pDate;
this.tags = pTags;
this.teaser = pTeaser;
}

public News(NewsVO newsVO)
{
this.id = newsVO.Id;
this.title = newsVO.Title;
this.body = newsVO.Body;
this.date = newsVO.Date;
this.tags = newsVO.Tags;
this.teaser = newsVO.Teaser;
}

public int Id
{
get { return id; }
set { id = value; }
}

public string Title
{
get { return title; }
set { title = value; }
}

public string Body
{
get { return body; }
set { body = value; }
}

public string Tags
{
get { return tags; }
set { tags = value; }
}

public string Teaser
{
get { return teaser; }
set { teaser = value; }
}

public DateTime Date
{
get { return date; }
set { date = value; }
}

public override int GetHashCode()
{
return (GetType().FullName + "|" +
tags + "|" +
teaser).GetHashCode();
}

}
}


here is the mapping to the class

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="MOE.Core" assembly="MOE.Core">
<class name="MOE.Core.Domain.News, MOE.Core.Domain" table="news" lazy="false">
<id name="id" column="id">
<generator class="identity" />
</id>

<property name="title" column="title" />
<property name="news" column="news" />
<property name="date" column="date" />
<property name="tags" column="tags" />
<property name="teaser" column="teaser" />

</class>
</hibernate-mapping>

Hi,

Can you check whether the Build Action for your .hbm.xml mapping file is set to "Embedded Resource"? (can be found in the properties view of your mapping file). If not, please choose Embedded Resource. This seems to be the typical error message when the Build Action is set to something else.

Best regards,

The mapping file is set as an embedded resource.
