Ok So I have an AS400/iSeries running v5r4. I have an application that was using classic NHibernate to connect and do some basic crud. Now I have pulled that app (which sat for 2 years) off the shelf of TFS and onto a new PC and cannot seem to get it running.

Here is my Hibernate Config:

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
      <property name="connection.provider">
        NHibernate.Connection.DriverConnectionProvider
      </property>
      <property name="dialect">
        NHibernate.Dialect.DB2400Dialect
      </property>
      <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
      <property name="connection.connection_string">
        DataSource=207.206.106.19;
        Database=AS400;
        userID=XXXXXX;
        Password=XXXXXXX;
        LibraryList=FMSFILTST,BEFFILT,HRDBFT,HRCSTFT,J20##X2DEV,GLCUSTDEV,OSL@@F3DEV;
        Naming=System;
        Initial Catalog=*SYSBAS;
      </property>
      <property name="use_outer_join">true</property>
      <property name="query.substitutions">
        true 1, false 0, yes 'Y', no 'N'
      </property>
      <property name="show_sql">false</property>
      <mapping assembly="BusinessLogic" />
    </session-factory>
  </hibernate-configuration>

I have all the proper DLL's included (NHibernate, castle, iesi, antlr3 , log4 etc). Also have this line in my web.config

<runtime>
    <assemblyBinding>
      <qualifyAssembly partialName="IBM.Data.DB2.iSeries" fullName="IBM.Data.DB2.iSeries,Version=10.0.0.0,PublicKeyToken=9CDB2EBFB1F93A26,Culture=neutral"/>
    </assemblyBinding>
  </runtime>

Yet I am still getting the following error as soon as I call

NHibernate.Cfg.Configuration().Configure().BuildSessionFactory().OpenSession();

The error is as follows

Unable to cast object of type 'IBM.Data.DB2.iSeries.iDB2Connection' to type 'System.Data.Common.DbCommand'

I am dying to get some help with this. Any assistance is appreciated. Thanks!
