Is there any very simple samples to donwload for beginners (on this website or anywhere else) ? I particulary research a sample that uses NHibernate.Mapping.Attributes.

thanks,

mathmax

There should be some samples linked from the Wiki. They don't use NHMA though, as far as I know.

Could you help me, please. I don't understand why this code doesn't work with the latest version of nhibernate whereas it works with nhibernate for .NET 1.1.

namespace NhbernateTest
{
class Program
{
static void Main(string[] args)
{
log4net.Config.XmlConfigurator.Configure();
NHibernate.Cfg.Configuration cfg = new NHibernate.Cfg.Configuration();
cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionProvider, "NHibernate.Connection.DriverConnectionProvider");
cfg.SetProperty(NHibernate.Cfg.Environment.Dialect, "NHibernate.Dialect.MsSql2005Dialect");
cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionString, ConfigurationManager.ConnectionStrings[1].ConnectionString);

cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionDriver, "NHibernate.Driver.SqlClientDriver");
System.IO.MemoryStream flux = new System.IO.MemoryStream();
NHibernate.Mapping.Attributes.HbmSerializer.Default.Validate = true;
NHibernate.Mapping.Attributes.HbmSerializer.Default.HbmDefaultAccess = "field.camelcase-underscore";

NHibernate.Mapping.Attributes.HbmSerializer.Default.Serialize(flux, System.Reflection.Assembly.GetExecutingAssembly());
flux.Position = 0;
cfg.AddInputStream(flux);
flux.Close();

NHibernate.ISessionFactory _sessionFactory = cfg.BuildSessionFactory();

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

NHibernate.ISession session = null;
NHibernate.ITransaction transaction = null;

try
{
session = _sessionFactory.OpenSession();
transaction = session.BeginTransaction();

session.SaveOrUpdate(newUser);

transaction.Commit();
}
catch(Exception e)
{
if (transaction != null)
transaction.Rollback();
throw;
}
finally
{
if (session != null)
session.Close();
}
}
}

[NHibernate.Mapping.Attributes.Class(Table = "users")]
public class User
{
private int id;
private string userName;
private string password;
private string emailAddress;
private DateTime lastLogon;

public User()
{
}

[NHibernate.Mapping.Attributes.Id(Name = "LogonId")]
[NHibernate.Mapping.Attributes.Generator(1, Class = "native")]
public virtual int Id
{
get { return id; }
}

[NHibernate.Mapping.Attributes.Property(Column = "Name")]
public virtual string UserName
{
get { return userName; }
set { userName = value; }
}

[NHibernate.Mapping.Attributes.Property]
public virtual string Password
{
get { return password; }
set { password = value; }
}

[NHibernate.Mapping.Attributes.Property]
public virtual string EmailAddress
{
get { return emailAddress; }
set { emailAddress = value; }
}

[NHibernate.Mapping.Attributes.Property]
public virtual DateTime LastLogon
{
get { return lastLogon; }
set { lastLogon = value; }
}
}
}


the error occurs at line " cfg.AddInputStream(flux); " and the message is : Could not compile the mapping document: (unknown)

Do you have an idea of the problem ?

Thank you in advance.

http://www.hibernate.org/Documentation/ ... otingGuide - see the general rule.

Do you think it is a bug ?

This is my first test using NHMA. I don't know how to make it work because I don't have any sample to see how NHMA works. The only one I found was this one. It wirked with .net 1 but not with .net 2.If you have any sample, even very simple, that uses NHMA I would be very interrested.

Did you actually visit the link?

yes it is a bug report. That's why I asked you if it is a bug.

Huh? Bug report? Where does it say "bug report"? It's a page to help people solve problems with NHibernate. In particular, the general rule I asked you to read and follow is:


So please show us the inner exception of the one you are getting.

InnerException :

Could not instantiate dialect class NHibernate.JetDriver.JetDialect, NHibernate.JetDriver

And the inner exception of that?

Impossible to load file or assembly 'NHibernate, Version=1.0.2.0, Culture=neutral, PublicKeyToken=154fdcb44c4484fc' or one of its dependencies. (Exception de HRESULT : 0x80131040)":"NHibernate, Version=1.0.2.0, Culture=neutral, PublicKeyToken=154fdcb44c4484fc

Okay, now you should have all the data you need to solve this on your own, or maybe with a bit of Google search.

Hint: you told us you're using the latest version of NHibernate (which is 1.2.0), and yet the assembly that could not be loaded belongs to NHibernate 1.0.2.
