After i had problems with lazy loading, I've read the article on
http://hibernate.org/42.html.

After that i know the problem is that i close the session after each request. I must define units of work and not close the session every time.

I also read about the sessioninview module. This module will solve the problem.

Is there any example / tutorial for this module. I can't find it on the web. I can only find small code-examples, but i don't know how to use it exactly.

Now i found this article: http://www.hibernate.org/43.html
I'm going to read it now. Is it a correct implementation of the sessioninview method?

You can find a good example here: http://www.codeproject.com/KB/architecture/NHibernateBestPractices.aspx

Thanks for the reply.
I've solved the problem a bit like the article.
It works now, and when i run the application, the connections to the database are closed after the requests. I think it's solved now.
