Starting as Nhibernate, with 1.2.1GA

When requesting that Configuration loads the mapping files, it throws an exception as follows: ( complete stack is at the end of this post ).

Initially, I was writing "hibernate-mapping" ( as per the user guide ); but after a look to nhibernate-mapping-2.2.xsd, I tried changing the element to nhibernate mapping.

NHibernate.MappingException was unhandled
Message="Remote(2,2): XML validation error: Could not find schema information for the element 'nhibernate-mapping'."
Source="NHibernate"
....

I don't understand what I'm doing the wrong way.

Any help would be invaluable.

TIA

Follows the coplete exception, and the "offending" file

The file

<?xml version="1.0" encoding="utf-8" ?>
<nhibernate-mapping assembly="Feeder-dll" namespace="Feeder" >
<class name="Remoteterminal" table="Remoteterminal" mutable="false" >
<id name="Remoteterminalid" column="Remoteterminalid" type="Int32" unsaved-value="0"
generator="" class="native" >
</id>
<property name="Description" />
<property name="Hwversion" />
<property name="Id" />
<property name="Ipaddress" />
<property name="Name" />
<property name="Serialnumber" />
<property name="Softversion" />

</class>
</nhibernate-mapping>

The mapping file should contain a xmlns attribute like this one:



Note that the value depends on the nh version, use "urn:nhibernate-mapping-2.0" for .NET 1.1 version,
"urn:nhibernate-mapping-2.2" for .NET 2.0 version,

Maybe this helps.

Thank you. Seeking in the examples, I found that advice ... but don't knew why the version change.
