code

config=new Configuration();
config.AddAssembly("NHTrial");
ISessionFactory factory = config.BuildSessionFactory();
ISession session = factory.OpenSession();
JLogin jlogin = (JLogin)session.Load(typeof(JLogin),txtlogin.Text);
string k=jlogin.Password;
Response.Write(k);


primary key is username.
based on username I would like to retrieve other details such as password. when I try to do it I get such exception.
