NHibernate in Visual Web Developer Express 2005

Hi everyone,

I've got a problem using NHibernate under Visual Web Developer Express.

I've created a new web project, added the NHibernate references and created a persistant class named Employe in the file Employe.cs.

I've created the mapping file "Employe.hbm.xml" and placed it in the same directory than "Employe.cs".

But when i launch the project, i've got this error :

Code:

Resource not found: NHib_log.Employe.hbm.xml

(NHib_log is the project's name)

The error is linked with this code :

Code:

config = new Configuration().AddClass(typeof(Employe));

I've tried to add directly the assembly but the error is similar.

I've made researches on the web and I think the problem comes from the fact that the mapping file "Employe.hbm.xml" has to be declared as an Embedded Resource in the build action propertie. But there is no build action propertie in visual web developer.
I tried other ways but nothing is working so far.

So, I don't know what to do, knowing that I'm pretty sure all the rest of the code is ok...

If somebody knows how to deal with that, thank you for the help !

I haven't used Express but I have used NHibernate in VS2005 without a project.

I place my class in the App_Code directory and my xml files in App_Code\Resources. Then I build the config like this:

Code:

Configuration cfg = new Configuration();
string basePath = System.Web.HttpContext.Current.Server.MapPath(@"~/App_Code/Resources/");
cfg.AddXmlFile(basePath+"Portfolio.hbm.xml");

My xml file starts like this. Note that the classes will live in the App_Code.dll assembly.

Code:

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="Domain.Portfolio, App_Code" table="PortfolioHead">
...

Hi,
thanks for your reply dfoderick.

I used your method and the "hbm.xml" file is recognized now !

But, it has brought another error :

Code:

Unable to recognize 'urn:nhibernate-mapping-2.0:hibernate-mapping'.

That is the code which is at the beginning of the "hbm.xml" file :

Code:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0" 
                   namespace="NH_Initiation" assembly="NH_Initiation">
  <class name="Nh_Initation.Employe, App_Code" table="e_emp">
...

I don't know if it comes from the same problem of embedded resource. I've searched but nothing is working.

If you or anyone else has a clue, thank you !

If you're using nhibernate beta 2 (version 1.2.0.2002) your mapping should look something like this (notice that the 2.2 differ):

Code:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<!--...-->
</hibernate-mapping>

Regards,

Cristian

Yeah, my xml file was for NHibernate 1.0. I'm going to upgrade soon to 1.2.

Glad you got it working.

Web developers create web form templates. This programming code is used to manage a consistent look and a smooth interface on a website. Its interface is easy to use design with a similar structure in all its pages. If your organization is trying to change business models, it is very difficult to change all pages. If you do not have a specific structure or specific models of web form, it will be harder for you to handle this.
