Could not create the driver from NHibernate.Driver.OracleDataClientDriver

Hi,

Just to update, the previous error was a red-herring, i removed the Dialect("NHibernate.Dialect.Oracle9Dialect")
and now get the above error message which i have been getting for ages.

I am attempting to connect to oracle 10 with visual studio 2010, i am using the follwing method:

public static ISessionFactory CreateSessionFactory()

    {
        FluentConfiguration idk = Fluently
            .Configure()
            .Database(OracleDataClientConfiguration
                .Oracle10
                .Dialect("NHibernate.Dialect.Oracle9Dialect")
                .Driver("NHibernate.Driver.OracleDataClientDriver")
                .Provider("NHibernate.Connection.DriverConnectionProvider")
                .UseReflectionOptimizer()
                .MaxFetchDepth(3)
                .AdoNetBatchSize(500)
                .ConnectionString(cs => cs
                .Server("PAUL-PC")
                .Port(1521)
                .Instance("xe")
                .Username("xxx")
                .Password("xxx")
                .Pooling(true)
                .StatementCacheSize(100)
                .OtherOptions(
                "Min Pool Size=10;Incr Pool Size=5;Decr Pool Size=2;")
            )
            // It does this automatically.. but I like to be explicit ;)
            .ProxyFactoryFactory("NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle")
            .ShowSql()
            )

           //.Mappings(m => m.FluentMappings.Add(typeof(PortalUserMap)).ExportTo("c:"))
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<PortalUserMap>().ExportTo(@"c:\"));


        idk.ExposeConfiguration(BuildSchema);

        return idk.BuildSessionFactory();
    }

and my mapping file looks like this when exported.

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true">

<id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
  <column name="ID" />
  <generator class="identity" />
</id>
<property name="UserName" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
  <column name="USER_NAME" />
</property>

</hibernate-mapping>

the code for this is:

public PortalUserMap()

    {
        Table("PortalUser");

        Id(x => x.Id, "ID").GeneratedBy.Identity();
        Map(x => x.UserName, "USER_NAME");
    }

I had previoulsy been geting errors with the oracle driver until i added the following lines:

.Dialect("NHibernate.Dialect.Oracle9Dialect")

                .Driver("NHibernate.Driver.OracleDataClientDriver")
                .Provider("NHibernate.Connection.DriverConnectionProvider")

that seemed to solve the problem, but now i get the mapping issue.

any help would be good.

Paul.
