Could not find the dialect in the configuration

[Michiel]

I get the following error when using NHibernate 2.0.1.400:

NHibernate.MappingException : Could not compile the mapping document:
Foo.Model.Mappings.Region.hbm.xml
System.InvalidOperationException : Could not find the dialect in the
configuration
"Could not find the dialect in the configuration"

I have one mapping file in a separate assembly. Its build action is
set to Embedded Resource. Here's the file:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Foo"
namespace="Foo.Model">
<class name="Region" table="Regions">
<id name="Id" column="Id" type="Int32" unsaved-value="0">
<generator class="native"/>
</id>
</class>
</hibernate-mapping>

My hibernate.cfg.xml is set to Copy always. Here's the file:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property
name="connection.provider">NHibernate.Connection.DriverConnectionProvider</
property>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</
property>
<property
name="connection.driver_class">NHibernate.Driver.SqlClientDriver</
property>
<property name="connection.connection_string">Data
Source=localhost;Initial Catalog=Foo;Integrated Security=True</
property>
<property name="show_sql">true</property>
</session-factory>
</hibernate-configuration>

Finally, this is the code to initialize the session factory:

Configuration configuration = new Configuration().AddAssembly("Foo");
sessionFactory = configuration.Configure().BuildSessionFactory();

What could be the problem?

I've had similar problems the last days.

Does your app.config contains a nhibernate section, this could also be the cause of this problem.

What I see also in your nhibernate.cfg.xml (and which causes also problems for me) is that you don't mention a ByteCode.provider (don't know yet what it does) like this:

    <property name='proxyfactory.factory_class'>NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>

Christian, if you use the trunk is better if you stay up to date.

Fabio,

thx for the info

[Michiel]

Well, I don't know about adding something that both of us don't even
know what it is for... also, I use the 2.0 release, nothing from the
trunk.

Thanks anyway!

hibernate.cfg.xml

I have it working now. I removed the AddAssembly("Foo") from the code,
and added a <mapping /> element to the configuration file. Now it
works, I don't know why the first way doesn't work though...

Thanks!

Michiel,

My mistake, I was playing with the trunk code, the last couple of days and had the same exceptions pupping, so I thought I could help a bit, only to realise I don't know much yet about NH.

The first way don't work because you are calling the AddAssembly method before call the Configure method.

Oh ok, then I misunderstood what the Configure() method does.

Thanks for clearing this up!
