We are currently using Spring.NET 1.1 RC1 with NHibernate 1.2 and we are in the process of building a new schema to replace a legacy database. What we're running into is a situation in which the two database schemas sometimes have name conflicts (e.g. both databases have a table called Order along with a domain class called Order). To mitigate this issue, we created separate domain and DAO assemblies so that we have something like Company.Product.Legacy.Domain.Order, Company.Product.Legacy.Dao.OrderDao, Company.Product.Domain.Order, and Company.Product.Dao.OrderDao and our mapping files use fully-qualified class and assembly names; e.g.:

<hibernate-mapping xmlns="..." namespace="Company.Product.Legacy.Domain" assembly="Company.Product.Legacy">
<class name="Order" table="Database.dbo.Order">
...
</class>
</hibernate-mapping>

The problem is that NHibernate is apparently using an unqualified reference to the Order domain class when validing the mapping files: "duplicate import: order refers to both Company.Product.Legacy.Domain.Order, Company.Product.Legacy.Domain and to Company.Product.Domain.Order, Company.Product.Domain."

Can anyone think of something we can do to allow NHibernate to recognize and use the correct classes in this situation?

Name and version of the database you are using: SQL Server 2005

The generated SQL (show_sql=true): none

Use in class mapping, like



Check out 5.1.2. hibernate-mapping

Could I please get a more extensive example on how to make this work, I've been struggling with:

---> NHibernate.MappingException: Could not compile the mapping document: (XmlDocument) ---> NHibernate.DuplicateMappingException: duplicate import: Documentation refers to both [MYNAME], [MYNAME], Version=1.0.0.0, Culture=neutral, PublicKeyToken=null and [MYNAME], [MYNAME], Version=1.0.0.0, Culture=neutral, PublicKeyToken=null (try using auto-import="false").

For some time now.

And I want to do it in code, with fluent nhibernate and automapping.

Solved it by removing all duplicates.
