The ProxyFactoryFactory was not configured

Question

Considering this example as a base example, I created the application but when I execute this application I am getting the following error.

The ProxyFactoryFactory was not configured. Initialize 'proxyfactory.factory_class' property of the session-factory configuration section with one of the available NHibernate.ByteCode providers. Example: NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu Example: NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle

The following is the code snippet I am using.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using NHibernate;
using NHibernate.Cfg;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Configuration cfg = new Configuration();
        cfg.AddAssembly("NHibernate");

        ISessionFactory factory = cfg.BuildSessionFactory();
        ISession session = factory.OpenSession();
        ITransaction transaction = session.BeginTransaction();
        User newUser = new 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();    
    }
}

And my app.config file looks like

    <?xml version="1.0" encoding="utf-8" ?>
    <configuration>
      <configSections>
        <section
          name="nhibernate"
          type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
        />
      </configSections>

      <nhibernate>
        <add
          key="hibernate.connection.provider"
          value="NHibernate.Connection.DriverConnectionProvider"
        />
        <add
          key="hibernate.dialect"
          value="NHibernate.Dialect.MsSql2000Dialect"
        />
        <add
          key="hibernate.connection.driver_class"
          value="NHibernate.Driver.SqlClientDriver"
        />
        <add
          key="hibernate.connection.connection_string"
          value="Server=localhost;initial catalog=nhibernate;Integrated Security=SSPI"
        />
        <!--<add value="nhibernate.bytecode.castle.proxyfactoryfactory, nhibernate.bytecode.castle" key="proxyfactory.factory_class" />-->
        <!--<property name="proxyfactory.factory_class">NHibernate.ByteCode.Linfu.ProxyFactoryFactory, NHibernate.ByteCode.Linfu</property>-->
<!-- I have tried both the lines but still getting the same error -->
      </nhibernate>
    </configuration>

I have LinFu.DynamicProxy.dll instead of linfu.dll. Will it work? If not, then from where do I get this linfu.dll? Or is there any other solution?

Answer 1

Assuming you have NHibernate 2.1 Alpha3, copy LinFu.DynamicProxy.dll and NHibernate.ByteCode.LinFu.dll from \Required_For_LazyLoading\LinFu to your bin (or references)

Then your configuration line should work:

<add key="proxyfactory.factory_class" value="NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu" />

As an aside, I prefer the hibernate-configuration section block for configuration.

Edit: Here's the relevant sections from my web configuration if you wanted to set up with hibernate-configuration instead of key/value pairs.

Also, it's possible to just put the hibernate-configuration part in its own file called hibernate.cfg.xml. You can then use the xsd nhibernate-configuration.xsd that's in the download to validate your configuration.

<configSections>
    <section name="hibernate-configuration"   type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
</configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
        <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
        <property name="default_schema">kennelfinder.dbo</property>
        <property name="connection.provider">
            NHibernate.Connection.DriverConnectionProvider
        </property>
        <property name="proxyfactory.factory_class">
            NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu
        </property>
        <property name="connection.connection_string">{Your connection string}</property>
        <property name="show_sql">false</property>
        <property name="connection.driver_class">
            NHibernate.Driver.SqlClientDriver
        </property>
        <property name="connection.isolation">ReadCommitted</property>
        <property name="use_proxy_validator">true</property>
        <mapping assembly="KennelFinder"/>
    </session-factory>
</hibernate-configuration>
