I have almost all the peices in place for a C# (visual studio 2008) console application with nhibernate.

I get a runtime error

NHibernate.MappingException: Could not compile the mapping document: BDM_Controller.Source.ORM.DB_Accounts.hbm.xml ---> System.InvalidOperationException: Could not find the dialect in the configuration
at NHibernate.Dialect.Dialect.GetDialect(IDictionary`2 props)

at BDM_Controller.SchwabProvider.transformAccountFile(CustomersDataTable customersDataTable) in C:\VisualStudioApps\BDM\Source\BDM Controller\Providers\Schwab\SchwabProvider.cs:line 103

It ccomplains that it can't compile my BDM_Controller.Source.ORM.DB_Accounts.hbm.xml config for an Accounts table

I have in the config:


<nhibernate>
<add
key="hibernate.connection.provider"
value="NHibernate.Connection.DriverConnectionProvider"
/>
<add
key="hibernate.dialect"
value="NHibernate.Dialect.MsSql2005Dialect"
/>
<add
key="hibernate.connection.driver_class"
value="NHibernate.Driver.SqlClientDriver"
/>
<add
key="hibernate.connection.connection_string"
value="Server=localhost;initial catalog=MvAccountInfoDB;Persist Security Info=True;User ID=<uid>;Password=<psw>"
/>
</nhibernate>


and the DB_ACcounts.hbm.xml is large but here is a partial source


<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace="BDM_Controller.Source.ORM."
assembly="BDM_Controller">
<class name="DB_Accounts" table="Accounts" lazy="false">
<id name="AccountNumber" type="String" length="9"/>
<property name="ShortTitle" type="String" length="36"/>
<property name="AlphaListNumber" type="String" length="7"/>
<property name="AdminOffCode" type="String" length="3"/>
<property name="AltAdmin1" type="String" length="3"/>
<property name="AltAdmin2" type="String" length="3"/>


...


<property name="ValuationFee1PaymentMethod" type="String" length="1"/>
<property name="ValuationFee2Schedule" type="String" length="3"/>
<property name="ValuationFee2PaymentMethod" type="String" length="1"/>
<property name="RelationshipCode" type="String" length="7"/>
</class>
</hibernate-mapping>

The messages are not clear if this is really a compile problem with the hbm.xml or it just can find the dialect, or do I need a dialect reference somewhere else?

This is from NHibernate 2.1.0.GA

Using MS SQL Server 2005 , Visual Studio 2008

any ideas o a fix would be appreciated.

I got further by doing a cnf.Configure("app.config") but still won't complie my hbm.xml.

I get:

NHibernate.MappingException: Could not compile the mapping document: BDM_Controller.Source.ORM.DB_Accounts.hbm.xml --->
System.InvalidOperationException: There is an error in XML document (1, 2). --->
System.InvalidOperationException: <hibernate-mapping xmlns='urn:nhibernate-configuration-2.2'> was not expected.

On the same hbm.xml above. I have stripped out the class section, same result, stripped out the parameters in the hibernate-mapping tag, same result (but you can see that it is looking at that tag.

I wish there were better more complete examples for the current version of the library.

Any ideas appreciated (if they solve the issue at hand, of course)

Thanks,

Hi there,

Try right click on your hbm.xml file and make sure it's Build Action is set to "Embedded Resource". See if that works!

Good Luck
