Hi,

I'm completely new to NHibernate. I've been trying hard following the QuickStart and other resources but hitting a number of obstacles.

Well, I'm developing using Visual Studio Web Developer Express. Understand that this is not a complete product. But I think I can still use it, just with more steps?

My present error is:
"Could not load type 'RHU.LicenseeCandidate, NHibernate, Version=1.0.2.0, Culture=neutral, PublicKeyToken=154fdcb44c4484fc', check that type and assembly names are correct"

I've the C# class LicenseeCandidate.cs file under the App_Code folder.
I've the mapping LicenseeCandidate.hbm.xml file under the same folder as well.

Part of the xml file:
"<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="RHU.LicenseeCandidate" table="LicenseeCandidate">"


My hiberante.cfg.xml file:

<?xml version="1.0" encoding="utf-8" ?>
<nhibernate xmlns="urn:nhibernate-configuration-2.0" >
<session-factory name="RHU">
<!-- properties -->
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string">Server=localhost;initial catalog=RAMS;User Id=;Password=</property>
<property name="show_sql">false</property>
<property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property>
<property name="use_outer_join">true</property>
<!--
these are different than the values in app.config so I can verify these
are being picked up
-->
<property name="command_timeout">444</property>
<property name="query.substitutions">true 1, false 0, yes 1, no 0</property>
<!-- mapping files -->
<!-- are now optional -->
<mapping file="C:\WebSites\RHUSpace\App_Code\LicenseeCandidate.hbm.xml" />
<mapping resource="RHU.LicenseeCandidate.hbm.xml" assembly="RHU" />
<!-- -->
</session-factory>

</nhibernate>


I don't quite understand the meaning of ASSEMBLY here. Should I simply treat as namespace that I"ve provided for the classes?



The error comes out on running the code:

Configuration cfg = new Configuration();
cfg.AddFile(System.Web.HttpContext.Current.Server.MapPath("~/App_Code/LicenseeCandidate.hbm.xml"));
cfg.Configure();

The 2nd line hits the error. i.e. when loading the xml mapping file.


I don't know. I've hit a number of issues. Earlier I was prompted that log4net couldn't be found. Finally, I copy log4net.dll to my project and gave it Reference and then it is ok. But documentation doesn't mention this... Or I missed something?


Your advice much much appreciated. Thanks!

Hi,


Or My problem is because I haven't named assembly correctly? But in Visual Web Developer, I don't see a place to name assembly at the Project properties page....

Anyone have experience?

thanks,

Hi JL,

I can't give you a direct solution to your problem, as I'm still quite new to nHibernate and .Net as well (and haven't done anything at all using ASP.Net)...

However, an assembly is nothing else as a file containing your application's code. This could be a DLL or an EXE. To rename the assembly, you simply rename your project, hence the file-name of the compliled code.

The error message seems to say, that it cannot find this specified assembly. Maybe it's named differently?

The namespace has nothing to do with the assembly name (though it's often useful to name them similiar, so they can be easily associated).

Kind regards, Marco...

RHU is your .NET namespace ?

if yes, try to put it into the class name

<class name="RHU.LicenseeCandidate, RHU" table="LicenseeCandidate">"

then be sure that your hbm.xml files are built as embedded resources; to check this click your hbm.xml file in Visual Studio Solution Explorer and check that Build Action property is set to Embedded Resource

If this does not help, start Your app in debugger and find out the full name of the object. With somthing like typeof(LicenseeCandidate).FullName

From that, You should be able to deduce what the name of class should be (AFAIK You can omit some parts from that string...)

or, the code You might use:
