I have a schema :

<class name="framework.modele.DBUser" table="users">
<id name="id" type="int" unsaved-value="0" >
<column name="id" sql-type="int" not-null="true"/>
<generator class="native" />
</id>
....
</class>



Than produce this file : (mapping objet)

/** @author Hibernate CodeGenerator */
public class DBUser implements Serializable {
....
}



I create this file: (entreprise object)

public class Utilisateur extends DBUser {


}

Is it a good way ?

Can i use the entreprise object in my form-bean of struts ? I don't want to write all the properties ... another time...

Is there another way ?


Thanks for your answer ! I'm ready to discuss about this.

I think this is not a good idea. You can find lot's of folks talking about application architecture in the other forum, however, so this is my 2cents.

I always have actionforms that are different than their Domain Model/Object model counterparts for the following reasons:

1. If you want to "remember" what a user types in to a form, (when a validation error occurs), you want to show the user exactly what the user typed, not what BeanUtils will convert it to.

2. What you want to do only makes sense when you have very simple screens that map 1:1 with the DB. Frequently the UI that is required does not easily map 1:1 with the db.

3. Check out some of Ted Husted's posts on why an action form is not an interface

have seen it?

what are you using?

so if i understand :

- i create a form bean with all properies
- i create a BOUser with the logic business
- i create a DBUser (java mapping from my schema) for db

form bean :

class formUser{
String name;
int idProfil;
..
}


class BOUser{
String name;
int idProfil;

void save(){

DBUser dbUSer=new ...();
beanUtil.copyproperties(dbUser,boUser);

session.save(dbUser);
}

void delete();
void update();
}

class DBUser{
String name;
DBProfil profil;

...hibernate part :

setDBProfil(DBProfil)...
getDBProfil(DBProfil)...

}


So in the application :
1. tranfert what users type in the form in formbean (made by struts)
2. In the action : use a beantutil to tranfert data from beanform to a new BOUser instance boUser.
3. Call boUser.save();

with the method :


It work fine except for my profil ? Is it a good way ?

Please help...
