I created a Class Project using Visual C# Express which has the Persistent Class file as well as the hbm file as embedded resource, and referenced the DLL in Visual Web Express (as suggested by people on the forum).

However i get a error like this :-

Could not find schema information for the element 'urn:NHibernate-mapping-2.0:hibernate-mapping'.

I am new to nHibernate. Please help.

Thanks.

Hibernate version:
1.2.0.1001

Mapping documents:
?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:NHibernate-mapping-2.0">
<class name="NHibernate.Examples.QuickStart.User, NHibernate.Examples" 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>

Code between sessionFactory.openSession() and session.close():
ISession session = factory.OpenSession();
ITransaction transaction = session.BeginTransaction();

NHibernate.Examples.QuickStart.User newUser = new NHibernate.Examples.QuickStart.User();
newUser.Id = "joe_cool";
newUser.UserName = "Joseph Cool";
newUser.Password = "abc123";
newUser.EmailAddress = "[email protected]";
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();
