Just following the NHibernate example delivered with Spring.NET and only change the table customer to a new table batch in database.
My scenario is:
A web project for the web site.
Create a new project for controller class. With the original example, these classes are put in folder app_code of the website

I can compile the project and the solution successfully. All xml files are modified properly. (replace all name like 'customer' with 'batch') try to run the application, got following error:

The error is because of web.xml file:
<object name="BatchEditController" type="NHibernateBatchEditController" scope="session">
<constructor-arg name="sessionFactory" ref="NHibernateSessionFactory"/>
</object>

Even I add namespace to rhe type type="RRM.Services.Controller.NHibernateBatchEditController", same error will come out.

Help please.
