O.K., let's have a look at your code:

> // The entity populate
> VUsuario usuarioDTO = new VUsuario();
> usuarioDTO.setCdUsuario(3389);
You needn't set CdUsuario, you have defined it as your id-attribute and told hibernate to generate it for you (<generator class="increment" />)
> usuarioDTO.setNmUsuario("Nina");
>
> // Get the session
> final InitialContext ctx = new InitialContext();
> final SessionFactory factory = (SessionFactory) ctx.lookup("java:/hibernate/BVServicoTesteFactory");
> Session sessao = factory.openSession();
>
> sessao.save(usuarioDTO)
O.K., so now you saved an object with id 3389.
>
> // Change the value to update other registry
> usuarioDTO.setCdUsuario(3380);
Now you change the id attribute of the object - you shouldn't do this! hibernate does identify objects by their id-attributes (that's why they're called id....), so from hibernate's view you got a new object!
> usuarioDTO.setNmUsuario("Gustavo");
> sessao.update(usuarioDTO);
Since the object has a new id you can't update it - there is no VUsuario with id 3380 in the database (you only stored one with 3389), so you should use save instead of update.

Hi piet,

Thanks for reply, my comment about that is id 3380 exists in database

I'm change the teste code to simple update the register, and the same error is show.

Code:

// The entity populate
VUsuario usuarioDTO = new VUsuario();
usuarioDTO.setCdUsuario(3389);
usuarioDTO.setNmUsuario("Gustavo");

// Get the session
final InitialContext ctx = new InitialContext();
final SessionFactory factory = (SessionFactory) ctx.lookup("java:/hibernate/BVServicoTesteFactory");
Session sessao =  factory.openSession();

// Try Update
sessao.update(usuarioDTO)

sessao.flush();
sessao.close();

Code:

You never specify in your hibernate configurations to map VUsuario.

I don't even think your save went through originally.

huangjd,

I´m using hibernate in Jboss as MBean. you dont need to declare .hbm.xml file in config.. this is automatic loaded.

I've never used Hibnerate as MBean before, but...

Quote in reference to the MBean setup... wrote:

Of course, you will want to change the attributes above.

Besides your error is even telling you the object isn't mapped.
