I try to run NHibernate.tool.hbm2net in nHibernateContrib.
I issue NHibernate.tool.hbm2net Employee.hbm.xml, but it seems generate nothing.

Does I miss any thing ?

Could you please post your code?

What I've done in my code is use NHibernate.Mapping.Attributes to declare my schema, and then build the .hbn.xml file from that. Once built, I update it in the project and *rebuild* (this is important -- embedded resources will not be updated unless the project is rebuilt).

Note that I pass in a coupe of extra parameters in the settings (e.g., the Assembly to be processed) because this code is from a library I reuse in different projects.

Code:
public static void ParseFromAttributes( IDictionary settings )
{
   Assembly assembly = (Assembly) settings["Assembly"];
   string directory = (string) settings["Directory"];
   Configuration cfg = CreateConfiguration( settings );
   System.IO.MemoryStream stream = new System.IO.MemoryStream(); // Where the information will be written in

   // Gather information from this assembly (can also be done class by class)
   HbmSerializer.Default.Serialize( stream, assembly );
   
   // this will create the .hbm.xml file in the specified directory
   string filename = string.Format( "{0}\\{1}.hbm.xml", directory, assembly.GetName().Name );
   StreamWriter fileStream = new StreamWriter( filename, false, System.Text.Encoding.UTF8 );
   stream.Position = 0;
   StreamReader r = new StreamReader( stream );
   fileStream.WriteLine( r.ReadToEnd() );
   fileStream.Close();

   // Now create the schema and build the tables
   stream.Position = 0;
   try
   {
      cfg.AddInputStream(stream);
      new NHibernate.Tool.hbm2ddl.SchemaExport(cfg).Create(true, true);
   }
   finally
   {
      stream.Close();
   }
}

internal static Configuration CreateConfiguration(IDictionary settings)
{
   string connectionProvider = (string) settings["ConnectionProvider"];
   if (connectionProvider == null)
      connectionProvider = "NHibernate.Connection.DriverConnectionProvider";
   string dialect = (string) settings["Dialect"];
   if (dialect == null)
      dialect = "NHibernate.Dialect.MsSql2000Dialect";
   string driver = (string) settings["ConnectionDriver"];
   if (driver == null)
      driver = "NHibernate.Driver.SqlClientDriver";
   string schema = (string) settings["DBSchema"];
   if (schema == null)
      schema = "dbo";

   string connectionString = (string) settings["ConnectionString"];

   Configuration cfg = null;
   try
   {
      cfg = new Configuration();
      cfg.SetProperty( NHibernate.Cfg.Environment.ConnectionProvider,   connectionProvider );
      cfg.SetProperty( NHibernate.Cfg.Environment.Dialect,         dialect);
      cfg.SetProperty( NHibernate.Cfg.Environment.ConnectionDriver,   driver);
      cfg.SetProperty( NHibernate.Cfg.Environment.ConnectionString,   connectionString );
      cfg.SetProperty( NHibernate.Cfg.Environment.DefaultSchema,      schema );
   }
   catch( Exception ex )
   {
      Utility.ErrorHandling.DumpException( ex );
      throw;
   }
   return cfg;
}

Perhaps I misunderstood your request in my earlier response. Do you want to generate C# code from an .hbm.xml file? Typically, you either create the .hbm.xml file manually or generate it from your code using NHibernate.Mapping.Attributes.

Thanks for your answer.
What I exactly want is how to generate c-sharp code from hbm.xml by hbm2net.

I try to run hbm2net someFile.hbm.xml, but it generate nothing, did I miss anything or what is the workaround ?

You might look at the code for the hbm2net NAnt task, also in NHibernateContrib. It calls hbm2net.exe. We used to use this (I wrote the task) but that was two years ago.

I'm working through the source for hbm2net and on my machine the hbm2net task is broken. Basically NVelocity coughs running under nant which obviously gives hbm2net problems as nvelocity is the default renderer. If anyone is sucessfully running the hbm2net task I'd like to figure out how my environment differs from yours.
