can anyone tell me what should be the mapping file structure for NHibernate 1.2.0.Currently I'm using this mapping file and it is giving an exception : MappingException.

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class
name="NHDemo.Status,NHDemo" table="status">
<id
name="statusCd"
type="long"
column="STATUS_CD"
>
<generator class="assigned" />
</id>
<property
name="statusDesc"
type="String"
column="STATUS_DESC"
length="50"
/>
<property
name="statusId"
type="long"
column="STATUS_ID"
length="18"
/>
</class>
</hibernate-mapping>

Problems with Session and transaction handling?

Read this: http://hibernate.org/42.html

change

urn:nhibernate-mapping-2.0

to

urn:nhibernate-mapping-2.2

But I'm still getting error :

An unhandled exception of type 'NHibernate.MappingException' occurred in NHibernate.dll

Additional information: Unknown entity class: NHDemo.Status

can you post the code that causes the exception?

namespace NHDemo
{
class Program
{
static void Main(string[] args)
{

Configuration conf = new Configuration();
conf.AddAssembly("NHDemo");
NHibernate.Mapping.Attributes.HbmSerializer.Default.Serialize("", System.Reflection.Assembly.GetExecutingAssembly());
conf.AddXmlFile("Status.hbm.xml");
ISessionFactory factory = conf.BuildSessionFactory();
ISession session = factory.OpenSession();
session.Flush();
Int64 x = 1;
Object y = (Object)x;
NHDemo.Status newUser = (NHDemo.Status)session.Load(typeof(Status),y);
session.Close();
conn.Close();
}
}
}

Mapping:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class
name="NHDemo.Status,NHDemo" table="status">
<id

column="STATUS_DESC"
length="50"
/>
<property
name="statusId"
type="long"
column="STATUS_ID"
length="18"
/>
</class>
</hibernate-mapping>

Class File:
namespace NHDemo
{
public class Status
{
/** identifier field */
private long _statusCd;

/** nullable persistent field */
private String _statusDesc;

/** nullable persistent field */
private long _statusId;

public Status(long statusCd, String statusDesc, long statusId)
{
this.statusCd = statusCd;
this.statusDesc = statusDesc;
this.statusId = statusId;

}

/** default constructor */
public Status()
{
}

public virtual long statusCd
{
get { return _statusCd; }
set { _statusCd = value; }
}

public virtual string statusDesc
{
get { return _statusDesc; }
set { _statusDesc = value; }
}

public virtual long statusId
{
get { return _statusId; }
set { _statusId = value; }
}

}
}

If you need any thing else kindly tell me.....actually this is really important because I have to use Hibernate queries in .NET

what happens if you just do this:

It is giving Identifier Mismatch Error

Yaa It's working Now actually that method takes an Object. Thanx.

Actually what the challenge i'm facing is that the application on which I'm working is built on JAVA with Oracle data base so they are using Hibernate.Now I need to Migrate from Java to .NET with the same data base and using the same HQL queries..... is there any way that it can be done.
