Hi All,
I am new NHibernate. I am getting "NHibernate:MappingException: Unknown Entity" exception. Following is the code and the mapping file I am using:
<? xml version="1.0" encoding="utf-8" ?>
< hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="SimpleExample.Customer, SimpleExample" table="Customers">
<id name="CustomerID" type="String" length="5">
<generator class="assigned" />
</id>
<property name="CompanyName" type="String" length="40"/>
<property name="ContactName" type="String" length="30"/>
<property name="ContactTitle" type="String" length="30"/>
<property name="Phone" type="String" length="24"/>
</class>
</ hibernate-mapping>
Configuration cfg = new Configuration();
cfg.AddAssembly("SimpleExample");
ISessionFactory factory = cfg.BuildSessionFactory();
using(ISession session = factory.OpenSession())
{
Customer customer = (Customer)session.Load( typeof(Customer),"ALFKI");
Msg.InnerHtml = "<BR>" + customer.ContactName + "<BR>";
session.Close();
}
Error:
Unknown entity class: SimpleExample.Customer
using(ISession session = factory.OpenSession())
Line 56: {
Line 57: Customer customer = (Customer)session.Load(typeof(Customer),"ALFKI");
Line 58: Msg.InnerHtml = "<BR>" + customer.ContactName + "<BR>";
Line 59: session.Close();
Where I am going wrong. Please let me know.
Thanks in Advance, Kalyan Raman Y.V
